Beijing said "no other country has the right to interfere" in the South China Sea, responding to Japan's stated intention to put discussion of the issue on the G7 summit's agenda.

Japanese Prime Minister Shinzo Abe proposed putting the subject on the agenda of the two-day summit in southern Germany that ended Monday with the hope of creating a joint announcement to influence China's moves within its territory.

"China enjoys indisputable sovereignty over the Nansha Islands and their adjacent waters. It is within the scope of China's sovereignty for China to build things on some of the Nansha Islands and reefs. No other country has the right to interfere," said Hong Lei, spokesman of China's Foreign Ministry, at a daily news conference on Monday.
