BANDAR SERI BEGAWAN, Brunei — US Secretary of State Hillary Clinton said Thursday that her talks in China this week were useful despite highlighting sharp differences between Washington and Beijing over key international issues from Syria's civil war to territorial disputes in the South China Sea. “Even when we disagree — believe me we can talk very frankly now — we can explore the toughest issues without imperiling the whole relationship," Clinton said in Dili, East Timor, a day after she met President Hu Jintao and other Chinese officials in Beijing. Clinton was criticized in official Chinese media during the visit, and she exchanged blunt words with Foreign Minister Yang Jiechi over how to end the bloodshed in Syria. She and Yang also pointedly disagreed over the South China Sea, where the Obama administration fears tensions stoked by nationalism will continue to rise over competing claims between China and its smaller neighbors, some of whom have their own overlapping claims. “As was evident yesterday, there is a huge amount going on where the United States and China need to consult," Clinton said, citing Iran and North Korea as well as Syria and the South China Sea. She said she personally and the US were “not going to shy away from standing up for our strategic interests and in expressing clearly where we differ." China is resisting a push by the US and other countries for UN sanctions against Syria to put pressure on President Bashar Assad's regime, saying the civil war there must be resolved through negotiations. Beijing also wants to negotiate several territorial disputes over the resource-rich South China Sea individually with its neighbors, rejecting the speedy implementation of a code of conduct to prevent clashes and multilateral negotiations that the US advocates. A senior US official traveling with Clinton from East Timor to Brunei, a member of the Association of South East Asian Nations that has claims in the disputed waters, said Washington believed that there would be a period of higher tensions for some time to come “no matter what" progress may be able to be made. “This is the new normal," the official said. “I think we have to be prepared for more tensions on these matters." The official spoke on condition of anonymity because he was not authorized to publicly discuss internal administration's assessments. — AP
