North Korea's Supreme People's Assembly is expected to formally approve leader Kim Jong Un's latest economic policies and possibly endorse a shift in U.S. strategy following his failed summit with President Donald Trump in Hanoi.

The assembly is to convene on Thursday.

Kim set the stage for the assembly meeting when he told a gathering of senior party members this week to "fully display a high sense of responsibility and creativity" in accordance with the "prevailing tense situation," according to state media reports.

The reports Wednesday made no mention of any comments regarding the Hanoi summit.

But Kim has previously used the opening of the assembly and the party political meetings that normally precede it as an opportunity to clarify his political priorities.
