Pixel by pixel, Taiwan maps out claims to contested South China Sea

Taiwan is finishing a project to map the disputed sea with high-resolution satellite imagery, generating an unusually detailed map and promoting Taiwan鈥檚 often overlooked maritime claims 鈥 which are as large as China's.

Taipei, Taiwan

Wang Cheng-gi laughs nervously as he discusses the detailed new maps of the disputed South China Sea being drawn in his corner office at Taiwan鈥檚 Department of Land Administration.聽

He鈥檚 skittish because results of the $2.98 million project to map out the minutia of every islet in the resource-rich ocean south of Taiwan are still classified. But聽when completed in about a year, the maps could reshape Taiwan鈥檚 often-overlooked maritime claim against more powerful Asian governments.聽

Seven countries lay claim to parts of the South China Sea, the strategic waters through which 50 percent of the world's shipping tonnage passes, and under which vast deposits of oil and gas may lie. Taiwan is pushing its first-ever mapping project to back up its own claims 鈥 which are as large as mainland China's 鈥 and to be one step ahead in the knowledge game of who is doing what in the contested waters.聽

High-resolution images聽

Mr. Wang鈥檚 desktop computer receives high-resolution images taken by two American-made satellites and beamed back to a private contractor. Five people on his staff use them to compile maps that they hope rival governments, including China, don鈥檛 yet have.

鈥淭he satellite images will let our government departments see the latest situations and understand which country is doing what,鈥 says Wang, a senior specialist overseeing the five-year project. 鈥淲e might find things we鈥檝e not seen before.鈥

One surprise to Wang so far is the activity of Vietnam, which is developing reefs and artificial islands in the Spratly Island, the largest South China Sea archipelago that Taiwan also claims. Hanoi has landfilled shallow reefs and built homes on some islets, according to images that can be blown up to about a square meter per islet.聽

鈥淚t鈥檚 really clear,鈥 Wang says. One Vietnamese landfill project spans 11 football fields, he says. 鈥淓veryone is talking about mainland China, but Vietnam is going all out.聽

鈥淭his year they鈥檝e landfilled to here, but maybe next year they will fill out to there,鈥 he says, pointing to spots on a handbill-sized map of the full ocean that he鈥檚 allowed to print out for discussion purposes.聽

Taiwan has extra reason to be sensitive toward Vietnam. In May, Vietnamese and Chinese vessels stood-off at sea after Beijing moved an oil rig into waters claimed by both countries. When 20,000 Vietnamese protested over the face-off, Taiwan was also drawn in 鈥 several of its factories were looted and burned, perhaps because they were mistaken for Chinese factories.聽

Large claims聽

Taiwan controls just two of the South China Sea鈥檚 hundreds of islets: the largest, 114-acre Itu Aba, and one of the dunes, which is too unstable for human occupation. Taiwan鈥檚 limited presence in the ocean has set back hopes of competing for undersea reserves that the US Energy Information Administration estimates at 11 billion barrels of oil and 190 trillion cubic feet of natural gas.

Taipei is gathering evidence to be taken seriously when it reiterates claims to the South China Sea, analysts say. Taiwan would otherwise be forgotten as a claimant, reducing future access to the less developed islets or resources at sea.

鈥淲e do not have the resources and manpower and firepower to sustain聽[our claims],鈥 says Alexander Huang, strategic studies professor with Tamkang University in Taiwan. The maps, he says, will give Taiwan 鈥渕ore evidence鈥 of its claim and show that 鈥渨e鈥檙e not shying away from this issue.鈥

Taiwan lays the same vast claims to the South China Sea that Beijing does. Both governments use the same perimeter 鈥 the so-called "nine-dash" line 鈥 to claim most of the sea's tiny islets. But Taiwan鈥檚 government, officially known as the Republic of China, says it laid the claim first, around 1947 after Japanese troops lost World War II and before Communist China was founded.

Taiwan has been self-ruled since the Republic of China government lost the Chinese mainland to the Communists in the聽Chinese civil war in the聽1940s and rebased in Taipei. Beijing claims sovereignty over Taiwan and its offshore territory, causing tension between the two sides and cutting Taiwan out of any regional maritime dialogue, as other governments recognize only the much larger China diplomatically.

Unwelcome in Asia?

The maps, Taiwan鈥檚 best at a scale of 1:5,000, could be a valuable intelligence asset. Scholars in Washington will welcome Taiwan鈥檚 maps as they look to democratic Taipei for details on China鈥檚 basis for claiming the sea, Mr. Huang says.

The United States has criticized China鈥檚 expansion in the sea, offered defense aid to the Philippines, and begun considering whether to lift a wartime ban on selling deadly weapons to Vietnam.

But Taiwan鈥檚 new gambit聽to revive its South China Sea claims聽would be less welcomed around Asia. The Philippines, which has extensive fisheries but little physical presence in the disputed ocean, is already asking the UN Convention on the Law of the Sea to review the basis for China鈥檚 claim. If the UN sided with the Philippines against China, Manila would have grounds to dispute Taiwan, as well.聽

鈥淭aiwan should be aware of the UN Convention because that impacts its own claims,鈥 warns Ramon Casiple, a blogger and political analyst in the Philippines.

Analysts expect Taiwan to follow up its maps at least by adding infrastructure to Itu Aba. It operates an airstrip there now and expects to finish a pier next year to accommodate naval and coast guard vessels. Vietnam has already voiced opposition.

鈥淚 think [Taiwan] is worried that other countries are claiming sovereignty in that area and if you don鈥檛 do something, you鈥檙e going to be left out,鈥 says Shane Lee,聽an聽international relations professor at Chang Jung 海角大神 University in Taiwan.
