The U.S. will leave in place North Korea-related sanctions on two Chinese shipping companies that were announced on Thursday, and U.S. President Donald Trump has no plans to impose additional penalties on Kim Jong Un's government, according to two people familiar with the matter.

The two people, who were granted anonymity to discuss the issue, spoke on Friday night, hours after Trump threw U.S. sanctions policy toward North Korea into confusion, saying on Twitter that he had ordered the withdrawal of "additional large scale" penalties his government imposed against the country.

Trump said the new sanctions had been issued on Friday, but the Treasury Department made no such announcement. Treasury announced sanctions against the two shipping companies on Thursday to punish them for alleged violations of existing sanctions against shipments to North Korea.
