CHINA-JAPAN-DIPLOMACY-WAR-HISTORY

A man takes a photo on the Marco Polo bridge, or Lugouqiao, in west Beijing on July 7, 2014, on the the 77th anniversary of the Marco Polo Bridge incident, a skirmish between Chinese and Japanese troops that served as a pretext for Tokyo's forces to seize Beijing and trigger the Sino-Japanese war. Chinese President Xi Jinping on July 7 commemorated the 77th anniversary of the official start of war with Japan, condemning those who "ignore the iron facts of history" in an oblique jab at Prime Minister Shinzo Abe.
