On November 15, Deputy Secretary of State John J. Sullivan met with Cambodian Foreign Minister Prak Sokhonn on the margins of the East Asia Summit in Singapore. The two officials exchanged views on the state of the U.S.-Cambodia relationship and discussed the U.S. vision for a free and open Indo Pacific. The Deputy Secretary urged the government of Cambodia to take tangible actions to promote national reconciliation, including freeing political prisoners, ending the ban on the political opposition, and allowing civil society and media to operate freely.
