Obama hasn’t won over China. From the Wall Street Journal:

BEIJING—China gave little hope that it would accommodate Washington on Iran and other thorny foreign-policy issues, despite the first real sign of flexibility in years over its exchange rate, which has been a growing source of friction with the U.S.
Foreign Minister Yang Jiechi sounded a defiant note Sunday, telling reporters it is up to the U.S. to mend frayed relations, which he said were hurt by American arms sales to Taiwan and by President Barack Obama’s meeting with exiled Tibetan spiritual leader the Dalai Lama. “The responsibility for the difficulties in China-U.S. relations does not lie with China,” Mr. Yang said.
