Beijing police intensified their crackdown on economic crimes last year, solving more than 2,100 cases involving contract fraud and credit card fraud, the city's public security bureau said on Wednesday.

Authorities also ramped up efforts to tackle emerging tax-related offenses, dismantling 11 criminal dens and detaining more than 90 suspects, the bureau said in a statement.

To address evolving challenges in economic crime, police across the capital have strengthened cooperation with financial regulatory bodies and expanded the use of advanced technologies in investigations.

Artificial intelligence has helped officers quickly identify and collect more than 100 leads related to money laundering and illegal financing, according to the bureau.

Police have also been encouraged to visit businesses, schools and communities to raise awareness about financial risks and promote crime prevention strategies, the statement said.
