US President Donald Trump has renewed sanctions on the DPRK, citing "an unusual and extraordinary threat" from its nuclear weapons. This came just 10 days after Trump said there was no longer a threat.  Meanwhile, the US and South Korea have agreed to indefinitely suspend two exchange program training exercises. The Pentagon said the move was to support implementing the outcomes of the Singapore Summit. It said additional decisions will depend on the DPRK continuing with productive talks in good faith.
