U.S. Secretary of State Mike Pompeo and his Turkish counterpart, Mevlut Cavusşoglu, agreed at a meeting in Singapore on Friday to continue to try to resolve issues between the two countries, the State Department said.

Washington has imposed sanctions on two of Turkish ministers over the trial of Andrew Brunson, a U.S. pastor accused of backing terrorism. Turkey has said the sanctions are unacceptable.

Pompeo met Cavuşoğlu on the margins of a meeting of regional ministers in Singapore. “They spoke about a number of issues, and had a constructive conversation. They agreed to continue to try to resolve the issues between our two countries,” State Department spokeswoman Heather Nauert said.
