BEIJING — The mainland will thoroughly review and lawfully address public tips it has received in order to crack down on a small group of diehard "Taiwan independence" separatists and their activities, a mainland spokesperson said on Wednesday.

Chen Binhua, spokesperson for the Taiwan Affairs Office of the State Council, made the statement in response to the creation of a public email tip-off system for reporting "Taiwan independence" hardliners.

Chen noted that since the system was introduced, people on both sides of the Taiwan Strait have supported the just cause of punishing those who seek "Taiwan independence" through concrete actions.

"This reflects their shared desire to oppose 'Taiwan independence' and promote cross-Strait exchanges and cooperation," Chen said.

Chen said the United Nations General Assembly (UNGA) Resolution 2758, which fully reflects the one-China principle, cannot be misinterpreted or even challenged.

Chen made the comment in response to a media query over the remarks of Taiwan's Democratic Progressive Party (DPP) authorities regarding the resolution.

Chen said the legal authority of the UNGA Resolution 2758 leaves no room for doubt and has been acknowledged worldwide.

It made clear that there is only one seat for China in the United Nations, precluding "two Chinas" or "one China, one Taiwan," Chen added.

Chen noted that the DPP authorities maliciously distorted the UNGA Resolution 2758 but the fact that there is but one China in the world and Taiwan is part of China can never be changed.

Chen said Chinese culture is a shared treasure among compatriots across the Taiwan Strait when asked about the popularity of the mainland-made video game "Black Myth: Wukong" in Taiwan.

Chen attributed the game's popularity on the island to its artistic merits and familiarity among Taiwan players as it draws inspiration from the classic Chinese novel "Journey to the West."

Citing several Chinese culture-based video games released by Taiwan companies that have been well received by young people across the Taiwan Strait, Chen said this proves the long-standing and profound Chinese culture is a shared treasure of compatriots on both sides of the Strait.

Industry data showed that the mainland's self-developed games generated overseas sales revenue of $8.55 billion and actual revenue of 147.3 billion yuan (about $20.7 billion) in the domestic market in the first half of this year, said Chen, adding the figures indicate a sound growth momentum.

"We welcome Taiwan youth to participate in the development of the mainland's gaming industry and support closer exchanges and cooperation between the gaming industries on both sides of the Strait," Chen said.
