China warned its rivals Wednesday against turning the South China Sea into a “cradle of war” and threatened an air defense zone there, after its claims to the strategically vital waters were declared invalid.
The surprisingly strong and sweeping ruling by a UN-backed tribunal in The Hague provided powerful diplomatic ammunition to the Philippines, which filed the challenge, and other claimants in their decades-long disputes with China over the resource-rich waters.
China reacted furiously to Tuesday’s decision, insisting on its historical rights over the sea while launching a volley of thinly veiled warnings to the United States and other critical nations.
“Do not turn the South China Sea into a cradle of war,” vice foreign minister Liu Zhenmin told reporters in Beijing, as he described the ruling as waste paper.
“China’s aim is to turn the South China Sea into a sea of peace, friendship and cooperation.”
Liu said China also had “the right” to establish an air defense identification zone (ADIZ) over the sea, which would give the Chinese military authority over foreign aircraft.
A similar zone set up in 2013 in the East China Sea riled Japan, the United States and its allies.
“Whether we need to set up one in the South China Sea depends on the level of threat we receive,” he said.
“We hope other countries will not take the chance to blackmail China.”
The Chinese ambassador to the United States, Cui Tiankai, was even more blunt over the ramifications of the verdict.
“It will certainly intensify conflicts and even confrontation,” Cui said in Washington on Tuesday.
China justifies its sovereignty claims by saying it was the first to have discovered, named and exploited the sea, and outlines its claims for most of the waterway using a vague map made up of nine dashes that emerged in the 1940s.
Those claims overlap with those of the Philippines, Vietnam, Malaysia, Brunei and Taiwan.
Manila, under previous president Benigno Aquino, launched the legal case in 2013 after China took control of Scarborough Shoal, a rich fishing ground within the Philippines’ exclusive economic zone and far away from the nearest major Chinese landmass.
China has also in recent years built giant artificial islands capable of hosting military installations and airstrips in the Spratlys archipelago, one of the biggest groups of islands in the sea.
– ‘No legal basis, unlawful’ –
Aside from stating that China’s historical rights were without “legal basis”, the tribunal ruled that its artificial island building and the blocking of Filipino fishermen at Scarborough Shoal were unlawful.
However the Philippines, under new President Rodrigo Duterte, declined to celebrate the verdict, saying on Tuesday only that it welcomed the ruling while calling for sobriety and restraint.
Duterte has repeatedly said he wants to improve relations with China, which plummeted under Aquino because of the dispute, and that he would seek Chinese investment for major infrastructure projects such as a railway for the impoverished southern Philippines.
His Foreign Minister, Perfecto Yasay, told AFP in an interview last week that the Philippines would seek to use the verdict as the basis for direct talks with China aimed at achieving a long-awaited code of conduct among rival claimants for the sea.
However China faced immediate pressure from Western powers, which insist they have legitimate interests in the dispute because of the need to maintain “freedom of navigation” in waters that hosts more than $5 trillion in shipping trade annually.
The United States emphasized on Tuesday that China, as a signatory to the United Nations Convention on the Law of the Sea, should accept the verdict.
“As provided in the convention, the tribunal’s decision is final and legally binding on both China and the Philippines,” State Department spokesman John Kirby told reporters in Washington.
Kirby called on all sides “to avoid provocative statements or actions”.
– ‘Reputational costs’
Australian Foreign Minister Julie Bishop warned China on Wednesday there would be “strong reputational costs” for ignoring the ruling, as she called for an end to Chinese island building.
“China seeks to be a regional and global leader and requires friendly relations with its neighbours. That’s crucial to its rise,” Bishop told national broadcaster ABC.
Military tensions in the sea had already spiked in the lead-up to the verdict.
China launched naval drills in the northern areas, while the US Pacific Command said it had deployed an aircraft carrier for flights to support “security” in the sea.
Taiwan, which was another loser in the verdict as its claims are very similar to those of China, sent a warship to the sea on Wednesday to protect its claims.
