The United States on Tuesday named former senior diplomat Joseph Yun to lead languishing talks with three tiny but strategically important Pacific Island countries, a signal that countering China remains a U.S. priority despite Russia's war in Ukraine.

The State Department confirmed the appointment of Yun, who served as U.S. special envoy for North Korea under former U.S. presidents Barack Obama and Donald Trump, in response to queries from Reuters.

"In light of the critical nature of these complex negotiations, President Biden is appointing Ambassador Joseph Yun as Special Presidential Envoy for Compact Negotiations," a statement from the department said.
