PENTAGON --- The Pentagon says China has canceled and postponed some military exchanges to protest the approval of new weapons sales to Taiwan.>> Major Stuart Upton says China has postponed or canceled senior level visits and exchanges on cooperation in disaster relief between now and the end of November. "The cancellation or the postponement of these meetings and these relations were a result of the Taiwan arms sales," he said. "And the fact is there has been no change to our policy over time that would force them or have them reacting to our arms sales to Taiwan.">> Major Upton could not immediately provide details of the canceled or postponed exchanges, but accused China of "continued politicization" of the bilateral military relationship.>> China's move comes after it objected to the Pentagon's approval of arms sales to Taiwan announced on Friday, that would allow the island to buy several types of missiles, 30 Apache attack helicopters, upgraded equipment for some of its military aircraft and a variety of other items.>> The defense department officially notified the congress of the approval, and members have 30 days to object. If there is no objection, Taiwan's government would still have to allocate the money to pay for any of the items. Some U.S. officials have complained in recent years that the island's government has been reluctant to approve money to buy modern weapons, and relies too much on the U.S. military for its defense.>> The arms package includes Patriot missiles for air defense, and Harpoon missiles, which are launched from submarines.
