China claims they aren't military bases, but their actions say otherwise.

Since 2014, China has been building islands in the middle of the South China Sea. What were once underwater reefs are now sandy islands complete with airfields, roads, buildings, and missile systems. In less than two years, China has turned seven reefs into seven military bases in the South China Sea, one of the most contentious bodies of water in the world.

The sea is one of the most important areas of ocean in the world. It’s estimated to hold 11 billion barrels of oil, 109 trillion cubic feet of natural gas, and 10 percent of the world’s fisheries. Most importantly, 30 percent of the world’s shipping trade flows through the South China Sea to the busy ports of Southeast Asia. It’s an incredibly important strategic area, and five countries currently claim some part of it.

Most countries base their claims off the United Nations Law of the Seas, which says a country’s territory extends 200 miles off its shores, an area called the exclusive economic zone, or EEZ. Any trade or resources that fall in a country’s EEZ belong to that country; they’re its sovereign territory. Any area that is not in an EEZ is considered international waters and subject to UN maritime law, meaning it’s shared by everyone. Every country in the region, which includes Malaysia, the Philippines, Brunei, and Vietnam, bases its claim to the South China Sea on the UN’s EEZ laws — except China.

China argues it has a historical claim to the South China Sea, dating back to naval expeditions in the 15th century. After World War II, the Japanese Empire lost control of the South China Sea, and China took advantage of the moment to reclaim it. On maps, it started drawing a dashed line that encompassed most of the South China Sea. This line became its official claim and is known today as the Nine-Dash Line, because it always has nine dashes. In 1973, when the UN law established EEZs, China reaffirmed its Nine-Dash Line, refusing to clarify the line’s boundaries and rejecting other countries’ claims.

Since then, tensions have built around who rightfully owns the South China Sea. The dispute has centered on the Spratly Islands, an archipelago at the heart of the South China Sea. Currently, China, Malaysia, the Philippines, and Vietnam claim some part of the Spratly Island chain. They’ve asserted their claims by putting small buildings, ports, and even some people on what are essentially rocks in the middle of the ocean.

But the Spratlys are very important, because whichever country can successfully claim them can extend its EEZ to include them, thus gaining miles of precious sovereign territory. This is why China began building up islands in 2014. By turning these rocks into military bases, the Chinese are now able to support hundreds of ships, bolstering their presence in the region. They are using fishing boats, surveillance ships, and navy destroyers to set up blockades around other countries’ islands and defend their own. This is all done very cautiously and in small steps in order to avoid sparking a wider conflict.

Since China began building islands, the disputes have not become violent. But tensions are building in the region. As China deploys more of its military to the Spratlys, other countries are getting nervous and building up their own islands. It’s a complex situation that will continue to gain international attention, for better or for worse.

    I saw a chinese news agency video covering about this issue. Then it said, "The Philippine Navy began to harass chinese fishermen." Although the "Philippine Navy" they are talking about is only a bamboo fishing boat with no guns or weapons.

  • I'm from the Philippines and I don't care that Malaysia, Vietnam or Brunei claims islands that we claim too, but a country that is using unrightful evidences just to get these islands.... nope...
  • @margustoo
    Why you guys show Taiwan under China?? They may claim it but they don't own that island..
  • In a egg hunt event Philippines: Wow I got a lot of eggs. Malaysia: Yeah me too. Vietnam: Oohhh I got a lot too. China: Hippity Hoppity this eggs is my property
  • I have also read news from the Chinese government which say that Vietnamese fishing boat is attacking their ship while you can clearly see small wooden Vietnamese fishing ship get ramped and sunk by Chinese big coast guard ship. That's why the Vietnamese are building more and more of their own coast guard to deal with china aggression
  • @wolfy4326
    China now: We have historical claims to these islands. China in 2030: We have historical claims to the Philippians. China in 2050: We have historical claims to the entire Asian continent.

    Great, ruin the few healthy coral reefs we have left. It's not like the great barrier reef is already on it's deathbed.

    Chinas evidence of territorial claim in a nutshell: China: Ancient Chinese ancestors stared at the stars and the whole universe. Therefore, the whole universe belongs to us.
