The blame for friction in Chinese-United States relations “does not lie with China,” and it is up to the United States to take steps to repair the frayed ties, China’s foreign minister repeated Sunday.  The minister, Yang Jiechi, said at a news conference that the administration of President Obama had seriously disrupted the relationship by announcing the sale of weapons to Taiwan and holding a White House meeting with the Dalai Lama, the Tibetan spiritual leader, in a three-week period this year.  China suspended military exchanges with Washington and threatened other reprisals after the American moves. American officials have expressed frustration with China’s trade policies, including its refusal to revalue its currency, and with Beijing’s reluctance to press Iran to open its nuclear program to international inspection.  Mr. Yang restated that reluctance on Sunday, saying that diplomacy with Iran was a better path than sanctions.  Two top American officials visited Beijing for talks on the relationship last week in what a State Department spokesman had called an attempt to “get back to business as quickly as possible.” But Chinese officials have yet to temper their public criticisms of American policies.  – New York Times
