Aso protests Chinese ships intruding into Japanese waters
Japanese Prime Minister Taro Aso lodged a protest with Chinese Premier Wen Jiabao over two Chinese survey ships that intruded into Japanese waters near the disputed Senkaku islands, a Japanese official said.
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.
