A Chinese mainland spokesperson on Monday warned the authorities of Taiwan against their "independence" speech, saying that their provocative actions were the roots for destabilizing cross-strait ties.

Ma Xiaoguang, a spokesperson for the Taiwan Affairs Office of the State Council, made the remarks in response to Lai Ching-te's recent claim that Taiwan is a "sovereign state".

Ma reiterated that Taiwan is an inseparable part of China, and China is steadfast in opposing "Taiwan independence."
