Taiwan's presidential office said on Saturday that the future of the island rests in the hands of its people and that mainstream public opinion is very clear in rejecting China's "one country, two systems" model.
Taiwan's Mainland Affairs Council in a separate statement called on China to abandon its "provocative steps of intrusion, harassment and destruction".
Both were responding to Chinese President Xi Jinping, who used a speech earlier in the day to pledge "reunification" between China and Taiwan.
