title: Tillerson calls China cooperation on North Korea 'uneven'
text: WASHINGTON (Reuters) - U.S. Secretary of State Rex Tillerson signaled on Wednesday that he would like more help from China in pressing North Korea over issues including its nuclear program. “Their cooperation I would say has been notable, but it has been uneven,” Tillerson told a congressional hearing. Washington is discussing North Korea with all of its allies, and it would top the agenda at high-level talks next week between U.S. and Chinese officials.
