Japan won't compromise on the stern wording of a UN resolution it sponsored seeking sanctions over North Korea's missile test and is pushing for an early vote on Monday despite opposition from China, Foreign Minister Taro Aso said Sunday. "To compromise because of one country which has veto power, even though most other countries support us, sends the wrong message," Aso told national broadcaster NHK, adding that a vote is expected on Monday. "We can't alter our stance." Japan's stiffening attitude comes ahead of a looming showdown over a resolution it introduced to the UN Security Council on Friday that would impose sanctions on North Korea for a series of rocket test-launches on Wednesday that rattled Northeast Asia and beyond. Among the missiles tested was one believed capable of reaching US shores.
