China pressed visiting US Secretary of State John Negroponte to reject a proposed sale of missiles to Taiwan, AP reported. During the meetings, Chinese officials firmly opposed the export and sale of weapons to Taiwan and the US maintaining official relations with Taiwan. Taiwan is trying to buy 218 Amraam medium-range air-to-air missiles and another 235 Maverick missiles at an estimated cost of $421 million. Wu Chi-fang, a Taiwanese Defense Ministry spokesman, said China has become a threat as it continues to build its military power. The US is currently Taiwan's main arms supplier.
