In Taiwan, the Democratic Progressive Party's Tsai Ing-wen took office on Friday as the island's new leader. The Chinese mainland's Taiwan Affairs Office described remarks by Tsai on relations across the strait as "an incomplete answer sheet".

Chinese mainland authorities have noticed that Taiwan's new leader had dodged the topic of the "One China Principle" in her inaugural address.

The State Council Taiwan Affairs Office says that Tsai Ing-wen "was ambiguous on the fundamental issue of the nature of cross-Straits relations".

In a statement, it said that her speech did not include any "explicit recognition of the 1992 Consensus and its core implications". It also said there was "no proposal of concrete ways to ensure the peaceful and stable development of cross-Strait relations."

It said that only affirmation of the political foundation that embodies the One China Principle, can ensure continued and institutionalized exchanges between the two sides of the Taiwan Strait.

Tsai Ing-wen, of the Democratic Progressive Party, won Taiwan's leadership election in January.

Her party has traditionally favored independence from China, and takes over after eight years under leader Ma Ying-jeou.

The State Council Taiwan Affairs Office warned that pursuing "Taiwan Independence" can in no way bring peace and stability across the Taiwan Strait. It said the Chinese mainland remains determined as ever to uphold national sovereignty and territorial integrity, and has even greater capability to do so.

But it also said China will keep expanding people-to-people exchanges across the strait, pushing forward cooperation in various fields and promoting economic and society integration. And China will not give up efforts to deepen connections between compatriots, and bringing Taiwan on board to build a shared future.
