THE Trump administration plans to announce new sanctions on North Korea, after declaring the country a state sponsor of terrorism.

North Korea has joined Iran, Sudan and Syria on America’s terror blacklist, a largely symbolic addition as the administration already has the authority to impose virtually any sanctions it wants on Kim Jong Un’s government over its nuclear weapons development.

As part of its “maximum pressure” campaign, President Donald Trump said the Treasury Department would impose more sanctions on North Korea and “related persons”, without hinting who or what would be targeted.

The move is part of rolling efforts to deprive Pyongyang of funds for its nuclear programme. “It will be the highest level of sanctions by the time it’s finished over a two-week period,” Trump said.

Secretary of State Rex Tillerson said on Monday the pressure campaign was starting to bite in Pyongyang, which is already facing unprecedented UN-mandated sanctions over its nuclear and ballistic missile tests.

Tillerson said anecdotal evidence and intelligence suggests the North is now suffering fuel shortages, with queues at petrol stations and revenues down.

In Tokyo, Japan’s Prime Minister Shinzo Abe welcomed the move, saying Japan supports the step as a way to increase pressure on North Korea.

But Chinese Foreign Ministry spokesman Lu Kang expressed concern, saying the situation is “highly sensitive” and that it would be “helpful to bring all parties back to the negotiation table instead of doing the opposite”.

Da Zhigang, a North Korea expert at the Heilongjiang Academy of Social Sciences, said the move “will arouse diplomatic reactions and hatred toward the US from North Korea” and could even prompt the North to resume missile tests.

In September, Trump opened the way for the US to punish foreign firms dealing with North Korea through an executive order expanding the Treasury’s ability to target anyone doing significant trade in goods, services or technology with the North, and to ban them from the US financial system.
