China is located in the east of Asia, on the west coast of the Pacific Ocean, with a land area of 9.6 million square kilometers, more than 18,000 kilometers of coastline in the east and south of the continent, and more than 4.7 million square kilometers of inland and border seas.

There are 7,600 large and small islands in the sea area, of which Taiwan Island is the largest, with an area of 35,798 square kilometers.

China shares borders with 14 countries and borders with 8 countries at sea.

Although China has a coastline of more than 18,000 kilometers, and the coastline of all islands is more than 32,000 kilometers long, with more than 4.7 million square kilometers of maritime land such as the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea, however, we can see that a series of large and small arc-shaped islands in the western Pacific Ocean tightly block China's gateway to the Pacific Ocean. The United States has heavily guarded this series of islands distributed in an arc, turning them into a so-called "island chain" used by Western countries to blockade the Asian continent.

The first island chain: refers to the chain of islands formed from the Japanese archipelago, the Ryukyu Islands, Okinawa in the north, the Taiwan Island of China, and the Philippine Islands and the Greater Sunda Islands in the south, of which Taiwan Island occupies the core strategic position.

The second island chain: refers to the Japanese archipelago in the north, through the Ogasawara Islands, the volcanic islands, the Mariana Islands, the Yap Islands, the Palau Islands, and extends to the Indonesian island of Hamarilla.

The island chain arose because of the Cold War, and the Western countries led by the United States and their Asia-Pacific vassals were the bastions of support, in order to contain, attack, defend, and block the socialist camp and countries headed by the Soviet Union and China.

In addition to the two island chains, the United States has co-opted India and fought terrorism in Pakistan and Afghanistan in order to blockade China at sea and land.

In addition to the U.S. containment, China has many maritime neighbors, and with the instigation and support of the United States, there are many disputes over maritime rights and interests between China and its maritime neighbors.

a. The Yellow Sea Question

b. The East China Sea issue

c. The South China Sea issue

The Yellow Sea, the western Pacific marginal sea, is a shallow sea occupied by the continental shelf, it is located between China and the Korean Peninsula, bordering China to the north and west, and the Korean Peninsula to the east.

In the second half of 2010, the United States and South Korea chose the location of the exercise in the Yellow Sea one after another, and in 1985, in the Battle of the Yellow Sea in the First Sino-Japanese War, China was defeated and humiliated the country.

From July 25 to 28, 2010, the United States and South Korea conducted the "Indomitable Will" joint naval exercise in the Sea of Japan, with more than 8,000 troops from both sides deployed, which was the largest military exercise conducted by the U.S. and South Korean militaries since 1976.

From 5 to 9 August, the ROK held a separate land, sea, air, and sea maneuver exercise in the West Sea (i.e., the Yellow Sea), with 4,500 ROK officers and soldiers participating in the largest anti-submarine military exercise in history.

From August 16th to 26th, the United States and South Korea held the "Ulchi Freedom Guardian" exercise in the Sea of Japan and the Yellow Sea.

The joint U.S.-South Korea military exercise, which was originally scheduled for September 5 but was postponed due to the typhoon, was held in the western waters of the Korean Peninsula (i.e., the Yellow Sea).

The East China Sea, from the north bank of China's Yangtze River estuary to Jeju Island in South Korea, adjacent to the Yellow Sea, northeast bounded by Jeju Island, Goto Islands and Nagasaki, south bounded by Nanao Island in Guangdong Province to the southern tip of the main island of Taiwan Province and the South China Sea, east to the Ryukyu Islands of Japan. It is located between Chinese mainland and Taiwan Island, Japan's Ryukyu Islands and Kyushu Island, and is connected to the Sea of Japan through the Tsushima Strait, bordering China's four provinces and cities of Shanghai, Zhejiang, Fujian and Taiwan, covering an area of more than 770,000 square kilometers.

The East China Sea is one of the world's famous fishing grounds and has found abundant oil and gas resources in the East China Sea.

The main problems facing China in the East China Sea are:

1. Disputes between China and Japan in the East China Sea

2. The Taiwan question

In the 60s of the 20th century, the United Nations Energy Agency (UNEA) released an investigation report, which predicted that there may be a large amount of oil and gas resources in the East China Sea. However, the key to the East China Sea issue lies mainly in the contradiction over how to demarcate the boundary of the East China Sea. Moreover, as the dispute between China and Japan on this issue becomes increasingly fierce, this issue has gradually become the focus of attention of the international community, and extraterritorial interference forces have also begun to pay attention to this area.

In the final analysis, the dispute between China and Japan over the East China Sea is a dispute over oil and gas resources in the East China Sea, and the dispute between China and Japan over oil and gas fields in the East China Sea stems from the dispute over the demarcation of the boundary of the exclusive economic zone between China and Japan.

According to the United Nations Convention on the Law of the Sea on the 200-nautical-mile exclusive economic zone, the exclusive economic zones of China and Japan are bound to overlap in the East China Sea, which is only 360 nautical miles at its widest point.

China advocates the extension of the continental shelf in the East China Sea to the Okinawa Trough in accordance with the principle of natural extension of the continental shelf established in the United Nations Convention on the Law of the Sea.

In order to avoid conflict, since the 90s of the last century, the Chinese side has been developing on the west side of the so-called "middle line" of the Japanese side, that is, the area that is not disputed.

After more than 10 rounds of talks from October 2004 to the present, the outline of China's proposition of "shelving disputes and joint development" has gradually become clear in the tug-of-war.

First, we should further determine the base points and baselines of all our territorial waters, and announce them to the world and file them with the United Nations.

Second, carry out in-depth propaganda in the country, enhance maritime awareness, and protect the monument of our territorial sea base point.

At present, there are still some contradictions between our exclusive economic zone and continental shelf and those of the neighboring countries along the coast, and our exclusive economic zone and continental shelf should be determined as soon as possible in accordance with the principle of peaceful consultations.

Fourth, it is necessary to build an effective and unified maritime law enforcement force, because maritime rights and interests must be embodied by maritime law enforcement forces to reflect our sovereign power and jurisdiction; for example, our fishery resources must be managed by the fishery administration, and anti-smuggling and anti-narcotics must be taken care of by the coast guard and customs.

Since modern times, there have been more than 260 imperialist aggressions against us from the sea, all of which have come from the sea. Therefore, building a strong people's navy is indispensable and an important part of our country's efforts to consolidate national defense and coastal defense
