China has suspended military exchanges with the United States after Washington's announcement of arms sales to Taiwan, widening rifts in their far-reaching relationship.
The Defence Ministry, in a strongly-worded statement carried by the official Xinhua news agency, condemned the proposed sale of weapons to Taiwan, which China considers an illegitimate breakaway province.
"Considering the severe harm and odious effect of US arms sales to Taiwan, the Chinese side has decided to suspend planned mutual military visits," Xinhua quoted the ministry as saying.
Xinhua later reported that the US defence attache in Beijing has been summoned by the government to protest at the deal.
Yesterday, the Obama administration told the US Congress of the proposed $6.4 billion sale to Taiwan.
The deal includes Black Hawk helicopters, Patriot "Advanced Capability-3" anti-missile missiles, and two refurbished Osprey-class mine-hunting ships.
Chinese Vice Foreign Minister He Yafei also told the US ambassador to China, Jon Huntsman, that the arms deal could jeopardise bonds with Washington, which has looked to China for help in surmounting the financial crisis, dealing with Iran and North Korea, and fighting climate change.
The US arms sales to Taiwan have joined trade imbalances, currency disputes, human rights, the Internet, and Tibet among rifts dividing the world's biggest and third-biggest economies.
Washington and Beijing have also recently traded angry words about Internet policy after the search engine giant Google earlier this month threatened to close its Chinese google.cn portal and pull out of China, citing censorship problems and hacking attacks.
In coming months Obama may meet the Dalai Lama, the exiled Tibetan leader China calls a dangerous separatist, adding to Beijing's ire with Washington.
Vice Minister He hinted the anger would be felt in a number of areas.
"The United States' announcement of the planned weapons sales to Taiwan will have a seriously negative impact on many important areas of exchanges and cooperation between the two countries," said He in the remarks, published on the Chinese Foreign Ministry's website (www.mfa.gov.cn).
He said the arms sales were "crude interference in China's domestic affairs and seriously harm China's national security", words notably tougher than Beijing's recent statements on the issue.
"This will lead to repercussions that neither side wishes to see," said He. He urged the US to halt the planned sales.
Apart from curtailing military ties with the United States, China's other options are less clear. Chinese President Hu Jintao is expected to visit the United States later this year, which could prevent the situation getting out of hand.
The biggest holder of US treasury debt, Beijing has shown no signs it would use that leverage in retaliation, which could damage the value of its own vast dollar holdings.
China curbed contacts with U.S. defence officials in 2008 after the then US President George W. Bush flagged the arms package for Taiwan.
After Washington cleared an earlier sale of Patriot missiles, China tested emerging military technology aimed at destroying missiles in mid-air.
"After the Obama administration stressed good relations with China last year, this will damage trust between the leaders of the two countries," said Liu Jiangyong, an international relations professor at Beijing's Tsinghua University.
"I think the price the United States pays will be heavier than the US may have anticipated," added Liu, who has advised leaders on foreign policy.
Taiwan's Defence Ministry welcomed Washington's decision.
"Its sales of arms to Taiwan gives us greater confidence in pushing for an amicable outcome in our relations with China, and will help promote peace in the Taiwan Strait."
Under President Ma Ying-jeou, since 2008 Taiwan has sought to ease tensions with the mainland and expand economic ties. But Taiwan also worries China could develop an overwhelming military advantage.
US officials have said Taiwan, which lags China in the balance of military power, needs updated weapons to give it more sway when negotiating with Beijing.
