New sanctions unveiled by the Trump administration that are intended to put a greater financial squeeze on North Korea may actually end up ensnaring American investors and companies who have developed joint ventures in China or frequently work with overseas suppliers and factories.

President Trump announced the expanded sanctions during a trilateral lunch Thursday with his counterparts in Japan and South Korea, declaring it “unacceptable” that various foreign entities continued to lend financial support to the “criminal [and] rogue” North Korean regime.
