The East China Sea. The pink line represents the both the regular Chinese ADIZ and the ECS ADIZ.

“We can only move forward, not backward. We will never let even 1 millimeter of our territory taken.” -Xi Jinping

China is reportedly deploying multiple warships near the borders of its East China Sea (ECS) air defense identification zone (ADIZ) for at least the next year.[i] The action by the PLA Navy raises concern for nearby Japan. According to the first article excerpt published in one of Japan’s leading newspapers, Yomiuri Shimbun, Japanese sources have observed a Jiangkai II-class [RG1] guided missile frigate and a highly capable air defense missile destroyer in the ECS.[ii] Japan is concerned by China’s operational posture within its unilaterally established ECS ADIZ. As the article explains, instead of allowing freedom of navigation in international airspace recognized in international law, China is operating as if its ECS zone falls under their jurisdiction, often warning foreign aircraft within the ADIZ that it will take “defensive emergency measures” if they do not leave immediately.

Concern surrounding the ECS ADIZ is not new. This zone differs from others as it intentionally overlaps portions of ADIZs maintained by Japan, Taiwan, and South Korea.[iii] The overlapping zones could create potential flashpoints, especially in areas in which disputed territories are involved. For example, both ADIZs maintained by China and Japan overlap the highly disputed, Japanese-administered Senkaku Islands, located adjacent to Taiwan. According to the second article excerpt, published through Tokyo-based nonprofit news agency Kyodo News, China’s Coast Guard drafted a plan to maintain its presence around the Senkakus, (also known as Diaoyu in China) throughout 2024. This decision came after Chinese President Xi Jinping pointed out the need for China to “constantly strengthen” its efforts to safeguard the sovereignty of the islands. The last excerpted article, also published in Yomiuri Shimbun, points out that China is strengthening its anti-access/area denial strategy while also exerting military pressure on Taiwan.[iv] The article describes China having four ships deployed around the clock, working closely with fighters, and increasing military activities. It adds that China will likely aim to block U.S. and Japan Self Defense Forces aircraft from entering the airspace in the event of a conflict over Taiwan. Meanwhile, an expert cited in the article points out that a Chinese invasion of Taiwan could include a concurrent “Senkaku contingency” because China claims the Senkakus are part of Taiwan.

“China Deploys Multiple Warships Around Self-Claimed ADIZ,” Yomiuri Shimbun (one of Japan’s five major newspapers), 28 January 2024. https://japannews.yomiuri.co.jp/politics/defense-security/20240128-165250/
China is deploying multiple warships around the clock in waters near the borders of the air defense identification zone that it has unilaterally established, The Yomiuri Shimbun has learned.

China is operating the zone on the premise that it is Chinese airspace. Aircraft that fly within its ADIZ are told to immediately leave.
Contrary to international custom, China unilaterally demands that aircraft flying in the zone follow Chinese authorities’ instructions. It also claims it will take “defensive emergency measures” if an aircraft fails to do so.

China started deploying at least three navy warships around the clock in waters around its claimed ADIZ, according to Japanese government sources. The three include an air defense missile destroyer, which is the Chinese version of an Aegis-equipped destroyer, and a frigate warship. Equipped with high-performance radar, air defense missile destroyers are highly capable of shooting down aircraft. The Chinese military aircraft repeatedly scramble in response to SDF aircraft, according to the sources. The Chinese military is believed to be strengthening its monitoring of SDF and U.S. military aircraft and warships in the East China Sea.

China’s monitoring capabilities were initially believed to be low, and it was thought that its establishment of the ADIZ would have no substantial impact. However, some observers are warning that China will have its warships, which are deployed around the clock, and fighters work together and increase its military activities. “It’s intended to block the SDF and U.S. military aircraft [from entering the airspace] in the event of contingencies in the Taiwan Strait,” said an SDF source.

“China Plans To Keep Ships Near Senkakus 365 Days in 2024,” Kyodo News (Tokyo-based non-profit news agency), 30 December 2024. https://english.kyodonews.net/news/2023/12/eb55266c4a9f-china-plans-to-keep-ships-near-senkakus-365-days-in-2024.html?phrase=Senkaku&words=Senkakus,Senkaku

China plans to keep its ships near the Japan-controlled Senkaku Islands in the East China Sea for 365 days in 2024 as leader Xi Jinping has called for bolstering Beijing’s sovereignty claim over the islets, sources familiar with the matter said Saturday.

During a rare visit by Xi on Nov. 29 to the command office for the East China Sea area of the China Coast Guard in Shanghai, the president pointed out the need for Beijing to “constantly strengthen” its efforts to safeguard the sovereignty of the islands, which China calls
Diaoyu, the sources said.

Xi, who also heads the Central Military Commission, the highest national defense organization, commented on a bilateral row over the Senkaku Islands, saying, “We can only move forward, not backward. We will never let even 1 millimeter of our territory taken,” the sources added.

“4 Chinese Warships Deployed Around Taiwan, Sources Say; Believe Ships Will Collaborate with Other Warships in East China Sea,” Yomiuri Shimbun (one of Japan’s five major newspapers), 30 January 2024. https://japannews.yomiuri.co.jp/politics/defense-security/20240130-165702/

China is believed to be using the ships to exert military pressure on Taiwan. If China and Taiwan enter an armed conflict with each other, an envisaged situation known as a Taiwan contingency, China likely will aim to block U.S. and other forces by using the ships in conjunction with other warships nearby. These warships are continually being deployed near the border of China’s air defense identification zone (ADIZ), which China has unilaterally declared over an area of the East China Sea.

China is strengthening its anti-access/ area denial (A2/AD) strategy, which restricts the military activities of other countries in its vicinity. The strategy aims to prevent U.S. forces from entering the first island chain that connects the Nansei Islands and the Philippines. The Chinese warships deployed near the ADIZ and around Taiwan are said to be almost in line with the island chain.“There’s a good chance that China will use force to make a move on the Senkakus in the future if Japan lets its guard down,” former Self-Defense Fleet Commander in Chief Yoji Koda said. “Japan needs to be fully prepared.”

Russia Claims Victory in Vostok 2022 Exercise

President Putin and Chief of General Staff Gerasimov, Vostok 2022, 6 September 2022.

One of Russia’s large-scale, annual military exercises, Vostok-2022, took place from 1-7 September. As with such exercises, it was widely covered in the Russian media, and as the brief excerpt from the Ministry of Defense’s TV Zvezda news network indicates, Russian forces again proved victorious. The article also stresses that Russia has not been isolated by its aggression against Ukraine, pointing out that 10 countries participated: Algeria, Armenia, Azerbaijan, Belarus, China, India, Kyrgyzstan, Mongolia, and Tajikistan. The article says that President Putin arrived at the Sergeevsky training ground to watch the final part of the exercises from a specially equipped command post. He watched his soldiers taking lines, liberating settlements, and forcing enemy retreats.

Vladimir Putin watched the maneuvers from a specially equipped command post. From there, he fully assessed the operational situation. Real-time data came even from the distant borders of the huge test site. All thanks to cameras installed in the fields with 32x magnification.

At the same time, the Chief of the General Staff had a connection with all the commanders-in-chief. The most up-to-date information was received from the training ground to the Supreme Commander-in-Chief, the technical characteristics of the weapons used were shown on the screen.

According to the legend of the exercises, the mock enemy “Vostochnye” attacked the “Northern” and their allies, wedging 200 kilometers into the depth of defense. The enemy was stopped, suffered losses, but retained reserves. From this point, the action begins to unfold - a grouping of troops, supported by artillery and tactical landing forces, hitting the enemy, taking lines and liberating settlements. Massed strikes by rocket troops and artillery, breaking the enemy’s reserves as well, are forcing the enemy to retreat.

A special feature of Vostok this year is the creation ofa coalition grouping of the armed forces of ten countries - Russia, Azerbaijan, Algeria, Armenia, Belarus, India, Kyrgyzstan, China, Mongolia, Tajikistan. Operational groups of the defense departments of Kazakhstan, Laos, Nicaragua and Syria were also involved….…The participants of the maneuvers noted that all the goals of the exercises were fulfilled. The issues of ensuring military security in the Eastern Region have been worked out.

Russian Navy Weaponizes Shipping Containers

Shipping Containers.

For the defense of Russian combat and auxiliary ships, an electronic warfare (EW) system is being developed. The EW system will be placed in ordinary 40-foot shipping containers.

The accompanying excerpted article from pro-Kremlin daily newspaper Izvestiya describes Russian efforts to place electronic warfare systems in standard 40-foot shipping containers. The Russian Navy is also experimenting with other shipping container-based weapon systems involving air defense, anti-ship, and surface and underwater unmanned reconnaissance capabilities. These shipping container-based weapon systems are not only intended to augment the capabilities of the Russian Navy’s ships, but also auxiliary ships (tugboats, transports, fuelers, etc.) that support the Russian Navy, and commercial ships if necessary. Shipping container-based weapon systems are likely to become more important to the Russian Navy as it transitions from larger ships, such as cruisers and destroyers, which have many capabilities to smaller ships, such as frigates and corvettes, with fewer capabilities. These shipping container-based weapon systems will permit these small vessels to expediently and cheaply add capabilities as required.

системы радиоэлектронной борьбы (The ‘noisy’ patrol: Russian ships will be protected by electronic warfare systems),” Izvestiya (pro-Kremlin daily newspaper), 8 September 2022. https://iz.ru/1392104/roman-kretcul/shumiashchii-patrul-rossiiskie-korabli-zashchitiat-sistemy-radioelektronnoi-borby

For the defense of Russian combat and auxiliary ships, an electronic warfare (EW) system is being developed. The EW system will be placed in ordinary 40-foot shipping containers. Thanks to this, the system can be easily installed on the decks of ships and vessels. Such protective "boxes" should reliably protect ships and vessels from enemy missiles and drones by way of electromagnetic interference. According to experts, as a result, this decision will significantly strengthen the protection of the country's coastal regions.

The Project 22160 ‘Vasily Bykov’ patrol ships will be the first to receive this electronic warfare systems. In the future, auxiliary vessels of the Russian fleet - tugboats, transports and others – could also acquire it…Initially, a weaker electronic warfare system was installed on Project 22160 ships, military historian Dmitry Boltenkov told Izvestia.“Apparently, they created a more powerful solution, of operational or strategic designation. Containers allow you to put the system on different ships,” the expert explained. “If necessary, it will be possible to build up the electronic warfare system of ship groups. They will be able to enter a given area and, in fact, completely “turn it off”. First, they will suppress drone control channels and communication systems. It will no longer be necessary to drive an electronic warfare vehicle onto a landing ship, instead they will simply put a container.

The Navy is also actively testing new container modules — with weapons and with various auxiliary equipment —including the Redut and Pantsir-M air defense systems, container modules with anti-submarine equipment, and container modules with cruise missiles. In particular, the Kalibr-NK cruise missiles. But the main possibility is that they can be adapted for the employment of underwater and surface unmanned vehicles of all types. This provides a reconnaissance capability over hundreds of kilometers…

Wood 01 Drift ice camp in the middle of the Arctic Ocean as seen from the deck of icebreaker Xue Long

China Developing Improved Equipment for Deep Sea, Polar Exploration

Drift ice camp in the middle of the Arctic Ocean as seen from the deck of icebreaker Xue Long.

“The Xuelong 2 is like a mobile laboratory at sea, sailing into many areas that were inaccessible in the past.”

China regards deep-sea[i] areas and polar regions as critical to its future development due to their abundant resources. President Xi Jinping even included them in his Holistic National Security Concept, which lays out domains that he regards as critical to China’s development and national security.[ii] However, both deep-sea exploration and polar regions pose significant technical challenges due to the extreme pressure or weather conditions encountered. As the following excerpts explain, China has made significant progress in overcoming these challenges.

The first excerpted article, from an early March 2023 edition of the official newspaper of China’s Ministry of Science & Technology, examines some of the equipment China has completed or is developing to explore deep sea and polar regions as part of its efforts to become a powerful maritime country. The article focuses on two technologies: icebreakers and deep-sea drilling rigs. The Xue Long 1 [GRLCUT(1] and Xue Long 2 [GRLCUT(2] icebreakers, originally based on a Ukrainian design, have improved China’s ability to explore polar regions. The article cites an acoustic engineer with experience studying polar environments, who highlighted how the Xuelong 2 had opened many previously inaccessible areas to exploration.

The latter half of the article focuses on deep sea drilling, noting the advances made with the “Manatee II” deep sea drilling rig, which is reportedly capable of operating at depths of 2,000 m or more and has set world records by drilling over 200 m into the ocean floor. A major priority for exploitation by this and future rigs is “combustible ice,” a mixture of frozen water and natural gas present on the sea floor in the deep sea. According to the article, the Manatee II has carried out exploration missions searching for combustible ice in many areas surrounding China, as well as for traditional offshore oil and gas deposits. Due to the experience from operating the Manatee, China has improved its technologies in this niche but important area, and the first of China’s next generation of deep-sea drilling ships is expected to be completed in 2024.[iii] It will reportedly be capable of drilling in waters deeper than 10,000 m.[iv] The minerals and natural gas potentially recoverable by these drills could create an economic bonanza and help China offset its reliance on imported energy. The second article is based on an interview with Sun Bo, Party Secretary of the China Polar Research Center Polar Research Institute of China, which is part of China’s Ministry of Natural Resources. Sun Bo noted how vital China’s second icebreaker, the Xuelong 2, completed in 2019,[v] has been for China’s polar exploration efforts, highlighting that having two icebreakers now allows China to effectively support research teams at both poles at the same time. While these articles underscore how China has clearly made important strides in overcoming technical bottlenecks, it might now face legal ones. The UN recently concluded negotiations about exploiting biological and mineral resources on the high seas, which might constrain China’s activities in polar and deep-sea regions.[vi]

Accelerating [China’s] development into a maritime great power and making good use of marine resources is not possible the important support of science and technology. To protect the marine ecological environment, it is necessary to strengthen basic research and fully understand the ocean’s riches; to develop marine resources, it is necessary to address the urgent requirements of improving development of technologies and equipment of scientific research for technology and equipment, and concentrate efforts to develop more “national strategic weapons.”[i]

“With the help of more and more advanced equipment, China’s polar scientific research has maritime, land and aerial capabilities.” Yin Jingwei [殷敬伟], vice president of Harbin Engineering University[ii], has long been engaged in research on polar acoustic technology….According to Yin [Xuelong 2’s] superior ice-breaking capabilities allow more scientific research facilities and supplies to be transported into the Antarctic regions. “It is like a mobile laboratory at sea, sailing into many areas that were inaccessible in the past.”

As of September 28, 2021, China has completed 12 Arctic expeditions. However, China is not an Arctic nation, and its deep-sea and polar-related research work started relatively late compared to other countries, and its support capabilities have also been limited to a certain extent. There are still many weak links and capabilities in the fields of polar science and technology research, polar equipment development, and deep-sea polar exploration. missing.

Yin Jingwei told the Science and Technology Daily reporter of that China does not yet have nuclear-powered icebreakers and underwater equipment capable of breaking ice in the polar regions, and the ability to collect maritime below the ice is also very weak. Additional efforts are needed to overcome technological and environmental hurdles to move forward.

www.kjrb.com/kjrb/html/2023-01/19/content_547740.htm?div=0In today’s world polar regions have become a “new frontier” for development and a focal point for global governance, a new high ground for technological competition, an area with new sea routes and a new source of resources. The China Polar Research Center of the Ministry of Natural Resources adheres to the principle of “understanding, protecting, and using” these regions proposed by General Secretary Xi Jinping, and is committed to providing support for China’s polar scientific research. China continues to improve its independent innovation capabilities and overall there is momentum to continue improvements. The China Polar Research Center independently built the “Xuelong 2” icebreaker with, filling a major gap in China’s capabilities required for polar scientific research and developed a way to use both the Xuelong and Xuelong two effectively in concert. This new pattern of “Double Xuelong” Polar exploration (one assigned to each polar region) has greatly improved the on-site support capabilities for China’s polar scientific investigations.
