A US academic is urging President Ma Ying-jeou (馬英九) to defuse tensions in the South China Sea by clarifying the “nine-dash line” and bringing Taiwan’s maritime claims into conformity with international law, especially the 1982 UN Convention on the Law of the Sea (UNCLOS).
Center for Strategic and International Studies senior Asia adviser Bonnie Glaser said that while the Ma administration has been “creative and constructive” in its East China Sea diplomacy, it has remained “mostly silent” as tensions have risen among claimants in the South China Sea.
“By clarifying its claims, Taiwan can remind the other claimants and the international community that it has important interests at stake in the South China Sea and is willing to be a constructive player in managing the disputes,” she said in a paper published this week by the center.
Glaser said that the primary source of instability in the South China Sea is the nine-dash line, which was originally an 11-dash line drawn by the Republic of China government in 1947.
She said that Jeffrey Bader, a former senior director for East Asia on US President Barack Obama’s national security staff, recently proposed that Washington discuss with Taiwan whether it can clarify its position on the nine-dash line.
“A first step could be for Taiwan to thoroughly review the Republic of China historical archives to fully understand the original intention behind the drawing of the 11-dash line,” Glaser said.
Taiwan should identify which of the land features that it claims are islands it believes are entitled to a 200 nautical mile (370km) exclusive economic zone (EEZ) and which are rocks that are only entitled to a 12 nautical mile territorial sea, she added.
In accordance with UNCLOS, the full EEZ limits could be claimed for islands in the central part of the South China Sea, Glaser said. EEZ claims for islands that are close to China’s coast or main archipelago of the ASEAN claimants would be limited to the mid-point in the waters from the islands claimed by Taiwan to the land belonging to the other claimant states, she said.
“Such a clarification of Taiwan’s claim would not necessitate revision of the [ROC] Constitution, as some experts have maintained, since Taipei would not need to modify its national boundaries or alter its sovereignty claims,” Glaser said.
In response to Taiwan’s positive approach, ASEAN might respond by supporting Taiwan’s inclusion in discussions with Beijing on establishing a code of conduct for the South China Sea, she said.
Most importantly, Taiwan’s action would put pressure on Beijing to also clarify its maritime claims in the South China Sea, which are based on the original 11-dash line that the People’s Republic of China inherited when it took over China in 1949, she said.
“If Mainland China were to follow in Taiwan’s footsteps and clarify its claims in accordance with UNCLOS, discussions could ensue on how to manage areas of overlapping claims, including joint development arrangements and peace and stability could be significantly enhanced in the region,” Glaser said.
She said that Beijing “would likely not welcome” a decision by Taiwan to clarify the meaning of the nine-dash line and abandonment of “historic rights” to natural resources in areas in the EEZ or continental shelf of other nations as required by UNCLOS.
