China claims more than 80 percent of the South China Sea and has constructed artificial islands there for potential development. Five other nations claim parts of the same maritime territory. China and Vietnam have accused each other of escalating tensions over Chinese oil exploration there, with confrontations between ships near the Paracel Islands. China and Japan agreed in November 2014 to disagree about century-old claims to a set of islands 1,000 miles to the northeast in the East China Sea. That was progress; a year earlier China had proclaimed an “air defense identification zone” over the islands. Taiwan stakes a claim, too and South Korea flew military planes through the self-proclaimed Chinese zone. President Barack Obama went to Japan in April 2014 and promised to defend the disputed islands, called Senkaku in Japanese and Diaoyu in Chinese and administered by Japan since 1972. China’s separate claim to a huge swath of the oil- and gas-rich waters of the South China Sea dates to 1947; there are now competing claims there by Vietnam, the Philippines, Brunei, Malaysia and Taiwan. China is locked in a separate disagreement with India over the two countries’ land border.
A territorial dispute became a U.S. presidential election issue in 1960: Richard Nixon assailed John F. Kennedy for refusing to commit to a nuclear defense of Taiwan’s rights to the islands of Quemoy and Matsu, which were also claimed by China. Nothing much happened and Quemoy is now best known for the meat cleavers its craftsmen made from the artillery shells fired at the island. History shows that China has tended to avoid inflaming its territorial disputes; Communist Party leaders have settled 17 of China’s 23 disputes since 1949, sometimes receiving less than 50 percent of the land at issue. Other nations aren’t always so conciliatory. A 1998-2000 border war between Ethiopia and Eritrea killed as many as 70,000 people. Argentina and the U.K. fought a 74-day war over the Falkland Islands in 1982 and 913 people died. Some territorial battles are waged at the ballot box and in courts. The U.K.’s 200-year dispute with Spain over Gibraltar appeared near resolution in 2002 when the two countries agreed to joint sovereignty. The deal collapsed when all but 200 of the area’s 18,000 people voted to remain a part of Britain. There are five official territorial disputes between the U.S. and Canada, which share the world’s longest land border and seem inclined to disagree agreeably. Some disputes get ugly, then go away. Peru and Ecuador fought the monthlong Cenepa War in 1995 over a remote patch of the Amazon rainforest, killing about 40 people. After mediation by neighbors and the U.S., a deal was signed in 1998. Peru and Ecuador are now at peace.
With China expanding its military, Japan starting to shed its postwar pacifism, and energy resources at stake, some analysts see the East China Sea and South China Sea conflicts as threats to peace that summon comparisons to Europe before World War I and World War II. On the other hand, the countries involved have much to lose by fighting. China and Japan, the world’s second- and third-largest economies, had trade of $344 billion in 2014, and China is Japan’s biggest trading partner. There is always danger, though, of a miscalculation or mistake — two planes colliding in midair, for example — that could inflame longstanding enmity.
