But it's really little wonder that China is trying to change the subject from its own problems, both foreign and domestic. For a start, Chinese President Xi Jinping will want no trouble from a U.S. president as he executes his anti-corruption campaign, the primary purpose of which many believe is to consolidate and further centralize his power. Meanwhile, Xi is also dealing with a restive empire, including a democracy movement in Hong Kong and unrest in Xinjiang, which has seen terror attacks against Chinese civilians and paramilitary officers.Dan Blumenthal: Chinese media have openly mocked Democrats' midterm lossChinese leader likely wants to distract from domestic problems, he writesObama should reinvigorate ties with Japan, he says
