TOKYO -- A group of Japanese lawmakers wants a team of experts to visit several disputed islands in a move that would likely raise tensions with China.

Japan's parliament on Monday debated whether to allow such a trip to the uninhabited islands -- called Senkaku in Japanese and Diaoyu in Chinese.

The experts would study development possibilities and environmental issues.

The hearing followed an unofficial "fishing" trip to waters off the islands Sunday by a half-dozen national lawmakers.

China has in the past warned Japan not to allow visits to the islands, which it claims are part of its sovereign territory.

Taiwan also claims the islands.
