BEIJING -- Any despicable act of crossing the line or making provocations on the Taiwan question will surely be retaliated against resolutely by China, and any attempt to thwart China's endeavor for reunification is doomed to failure, a Chinese foreign ministry spokesperson said Monday.

Spokesperson Lin Jian made the remarks at a daily press briefing, in response to a related query about the military drills code-named "Justice Mission 2025" around Taiwan Island organized by the Eastern Theater Command of the Chinese People's Liberation Army starting from Monday.
