Here's a breakdown of the trip:
Nov. 12-13 -- Tokyo. Obama will meet with new Japanese Prime Minister Yukio Hatoyama. (Perhaps they'll commiserate over the recent loss of the 2016 Olympics to Rio de Janeiro; Chicago and Tokyo were both finalists.)
Nov. 13-15 -- Singapore, for the Asia-Pacific Economic Cooperation conference.
Nov. 15-18 -- China, with stops in Shanghai and Beijing. The president will meet with Chinese President Hu Jintao.
Nov. 18-19 -- Seoul. Obama will meet with South Korean President Lee Myung Bak and visit U.S. troops who are stationed near nuclear-armed North Korea.
