WASHINGTON: US President Donald Trump has rolled out fresh sanctions against North Korea-linked shipping assets, hailing the package as the “heaviest sanctions ever” levied on the Pyongyang regime.

Trump used a speech to conservatives just outside Washington to step up his campaign of “maximum pressure” designed to force North Korea to roll back its weapons programs.

“We imposed today the heaviest sanctions ever imposed on a country before,” Trump claimed at the end of a lengthy campaign-style address Friday.

In light of past US embargoes, that is likely an overstatement, but Treasury Secretary Steve Mnuchin confirmed the sanctions covered “virtually all the ships” North Korea is “using at this moment in time.”

Speaking to reporters in Pyeongchang Saturday on a visit to the Winter Olympics, White House spokeswoman Sarah Sanders said: “Hopefully we’ll see a change on the part of the North Koreans to start to denuclearise the peninsula, that’s what our focus is.”

She added: “I can tell you the president won’t make the mistakes the previous administration has and be soft or weak.”

Trump’s administration is locked in a nuclear standoff with Pyongyang, which is trying to develop missiles that could deliver an atomic weapon to major US cities.

The latest sanctions are designed to put the squeeze on North Korea’s already precarious economy and fuel supply.

US prepares crackdown on evaders

Meanwhile, Reuters reported that the Trump administration and key Asian allies are preparing to expand interceptions of ships suspected of violating sanctions on North Korea, a plan that could include deploying US Coast Guard forces to stop and search vessels in Asia-Pacific waters, senior US officials said.

Washington has been talking to regional partners, including Japan, South Korea, Australia and Singapore, about coordinating a stepped-up crackdown that would go further than ever before in an attempt to squeeze Pyongyang’s use of seagoing trade to feed its nuclear missile programme, several officials said.

While suspect ships have been intercepted before, the emerging strategy would expand the scope of such operations but stop short of imposing a naval blockade on North Korea. Pyongyang has warned it would consider a blockade an act of war.

The US-led initiativ shows Washington’s increasing urgency to force North Korea into negotiations to abandon its weapons programmes, the officials said.
