China hinted it was drawing a line under its dispute with Singapore over Lee Hsien Loong's visit to Taiwan days ahead of his taking over as prime minister, but foreign ministry officials took the opportunity to warn Japan over an unscheduled stop there by Taiwan's premier, a surprise blamed on a typhoon. In Lee's first policy speech since becoming premier this week, he said his country could not and would not support Taiwan if mainland forces attacked the island to quash moves to establish independence. Chinese Foreign Ministry spokesman Kong Quan said China had taken note of Lee's comments and said they were conducive to peace and stability in this region. At the same time Kong expressed ï¿½deep concernï¿½ over Taiwan Premier Yu Shyi-kun's unscheduled stop in Okinawa en route to Taipei when his plane was diverted for weather reasons. "We are resolutely opposed to Taiwan leaders engaging in political activities under any pretext in countries with diplomatic relations with China," Kong said, adding that China had asked Japan ï¿½to handle this issue appropriatelyï¿½.
