The House of Representatives committee on security affairs endorsed a resolution Tuesday expressing regret at the landing of seven Chinese activists on one of the disputed Senkaku Islands last week.
The resolution was passed unanimously by committee members from the ruling coalition and the Democratic Party of Japan.
The resolution said that from the viewpoint of international law and history, the disputed islands clearly belong to Japan.
The resolution called on the state to take all possible measures to prevent a recurrence of similar incidents and beef up diplomatic efforts for maintenance of the territorial integrity.
The Senkakus, located about 400 km west of Naha, Okinawa Prefecture, are claimed by Japan, China and Taiwan.
