This meeting took place during the delegation's visit to Thailand from 30 March to 3 April 2024.

On this occasion, both parties reaffirmed their commitment to promote cooperation between Thailand and the U.S. in areas of security and law enforcement, enhancing partnership to address trafficking in persons, which is becoming a transnational challenge, particularly those related to cyber scams. They also exchanged views on Thailand's efforts to combat human trafficking, as well as significant legislative developments in Thailand and in the region regarding human rights protection.

Furthermore, Director-General also requested support from the delegation to encourage members of the U.S. House of Representatives to consider joining the U.S.-Thai Alliance Caucus, which was established in the U.S. Congress to support Thailand-U.S. cooperation.
