China and Russia recently initiated joint naval drills in the Sea of Japan, a significant geopolitical event given the strategic importance of the region. These exercises are likely to have implications for regional security dynamics, as both countries are increasing their military cooperation in response to growing tensions with Western powers and neighboring nations.

About the Sea of Japan (East Sea)

The Sea of Japan, also known as the East Sea, is a marginal sea of the western Pacific Ocean, surrounded by key nations and holding great strategic importance.

Geographical Features:

  • Location: The Sea of Japan is bordered by:

    • East: Japan and Sakhalin (a Russian island).

    • West: Mainland Russia, North Korea, and South Korea.

  • Area: The sea covers approximately 978,000 square kilometers.

  • Shape: It is elliptical in shape, with its main axis extending from southwest to northeast.

  • Connections:

    • South: Connected to the East China Sea via the Tsushima and Korea Straits.

    • North: Connected to the Okhotsk Sea via the La Perouse and Tatar Straits.

    • East: Linked to the Pacific Ocean through the Tsugaru Strait and the Inland Sea of Japan via the Kanmon Strait.

Physical Characteristics:

  • Depth: The average depth of the Sea of Japan is 1,667 meters, with the deepest point being the Dohoku Seamount, an underwater volcano.

  • Climate: The relatively warm waters of the Sea of Japan play a significant role in creating Japan’s mild climate.

  • Water Balance: The sea has limited freshwater inflow from rivers (less than 1%), and its water exchange is predominantly influenced by inflows and outflows through the connecting straits.

  • Tides: Due to its almost enclosed nature, the Sea of Japan experiences minimal tides, similar to the Mediterranean Sea.

Biological Productivity:

The Sea of Japan is rich in oxygen, contributing to its high biological productivity, making it a valuable resource for marine life and fishing activities.

Economic Activities in the Sea of Japan

  • Mineral Resources: The sea is known for its rich mineral deposits, including magnetite, natural gas, and petroleum, making it a region of interest for economic exploitation.

  • Ports: The Sea of Japan serves as a vital route for trade and commerce, with important ports in the bordering nations:

    • Russia: Vladivostok, Sovetskaya Gavan, Nakhodka, Alexandrovsk-Sakhalinsky, and Kholmsk.

    • North Korea: Hamhung, Chongjin, and Wonsan.

    • Japan: Niigata, Tsuruta, and Maizuru.

Strategic Importance and Military Activities

The Sea of Japan has long been a critical area for military strategy, particularly due to its location between major powers like Russia, China, Japan, and the Korean Peninsula. The recent joint naval drills between China and Russia underscore the growing military cooperation between the two nations, which has raised concerns among regional players such as Japan and South Korea.

These drills serve to bolster the military presence of both China and Russia in the region, especially as tensions rise over territorial disputes and the growing military presence of the United States and its allies in the Indo-Pacific. The joint drills also come at a time when Russia is facing increased isolation due to the war in Ukraine, and China is expanding its influence across the region.
