BEIJING -- It is legitimate and necessary for police to seek clues on illegal separatist acts, said a mainland spokesperson on Thursday.

The police of Quanzhou, Fujian province, on Thursday issued a bounty notice for clues on criminal and illegal activities of two Taiwan social media influencers who acted as enforcers and accomplices for secessionist forces.

According to Chen Binhua, spokesman for the State Council Taiwan Affairs Office, those two people have long made inflammatory remarks inciting separatism and disparaging the mainland's policies and measures designed to benefit Taiwan and its people.

Chen expressed the hope that compatriots on both sides of the Taiwan Strait would actively report clues about such illegal activities and urged them to firmly oppose all forms of "Taiwan independence" separatist actions.
