"The U.S. side's act has seriously blocked bilateral exchanges and contacts in various fields, including high-level visits between the two armed forces," Foreign Ministry spokesman Qin Gang told reporters Tuesday in Beijing, Xinhua reported.

"The U.S. side should take full responsibilities for the current situation of damaged military-to-military ties."

China's earlier attack came after the U.S. Defense Department announced it had requested the U.S. Congress to authorize $6.5 billion in advanced armaments for Taiwan, including 330 Patriot missiles and 30 Apache attack helicopters. U.S. officials were quoted as saying the sales were needed to promote strategic balance in the region.

On Tuesday, Qin said China, which claims Taiwan as part of its territory, has always promoted Sino-U.S. military exchanges for many years.

But he said the latest proposed arms sales to Taiwan has "undoubtedly poisoned the good atmosphere of the military relations between the two nations, seriously endangered Chinese national security, and severely hindered the exchanges in various fields, including the high-level exchanges between the two armed forces."
