The first of three public hearings on whether Taiwan should ease its ban on Japanese food imports imposed after the 2011 Fukushima nuclear crisis was canceled Sunday amid shouting, table pounding, and physical altercations.

Hundreds of protesters mobilized by the main opposition Kuomintang clashed with police outside the hearing venue in New Taipei City. A truck parked outside bore placards calling President Tsai Ing-wen "Japan's servile follower" and demanding her resignation.

Participants allowed inside criticized organizers for blocking people outside from entering. One opponent who prepared her own microphone said the hearings are meaningless because Tsai has the final say on the matter.
