TAIPEI (Kyodo) A planned protest voyage from Taiwan to the Japan-administered Senkaku Islands was called off just hours before the scheduled departure amid government pressure, according to one of its organizers.

Some 40 activists who dispute Japan's claims of sovereignty over the East China Sea islets scuppered their voyage after the owner of the boat slated for the journey backed out of an agreement to rent them the vessel, Huang Hsi-lin, a municipal council member in Taipei County, said Monday.

The activists said Tuesday that Taiwan's National Security Council pressured them and the boat owner to cancel the trip.
