According to the ministry, the man went to Shanghai in May. The US authorities shared evidence with their Chinese counterparts and asked them to investigate. Chinese police located the suspect and arrested him in June.

The police investigated the man's history in China, and found no evidence of him sexually abusing children in China.

According to the ministry, China responded promptly to the US request, reflecting China's resolve to deny safe haven to fugitives from other countries.

The ministry said China and the US will continue to enhance communication and mutual trust and deepen judicial cooperation, such as the sharing of intelligence, to fight transnational crimes.

"We also hope to conduct more such judicial cooperation with other countries in the future," added Tian Lixiao, deputy director of International Cooperation Bureau of the ministry, according to a report of China News Service.
