BEIJING, July 12 (Xinhua) -- A mainland spokesperson on Friday slammed Tsai Ing-wen and the administration of Democratic Progressive Party (DPP) for disregarding Taiwan people's wellbeing and "banking on foreign forces to build themselves up."

Ma Xiaoguang, a spokesperson for the State Council Taiwan Affairs Office, made the remarks when responding to a question about Tsai's "transit" in the United States.

For their own selfish purposes, Tsai Ing-wen and the DPP administration has attempted to challenge the one-China principle with the help of foreign forces and seriously damaged peace and stability across the Taiwan Strait, he said.

"The DPP administration has wrongly judged the situation and turned against the will of the people, and will not escape the fate of being abandoned by the people," he said.

"No element should underestimate our resolve and ability to safeguard national sovereignty and territorial integrity," Ma added.
