Chinese ships enter Japan's territorial waters:
Three Chinese government ships entered Japanese territorial waters on Friday, the coastguard said, days after Japan's premier vowed to expel any Chinese landing on a chain of disputed islands.
Chinese naval vessels were spotted in waters near a southern Japanese island Tuesday, marking the first time that the nation's ships have closed in on Japanese waters since diplomatic relations between the two countries took a nose-dive after Japan nationalized a chain of disputed islets.
