This week, China’s president and Japan’s prime minister announced a new agenda for China-Japan relations, ending the worst era of antagonism in their two countries’ relations since the end of World War II. In the first state visit by a Chinese leader to Japan in a decade, Hu Jintao and Japanese counterpart Fukuda Yasuo put aside difficult years of deep confrontation between their two countries. Promising to promote “mutually strategic interests,” they committed to annual state visits and to a new agenda of cooperation on issues such as global climate change and promoting peace on the Korean Peninsula.
