According to a report in The Financial Chronicle, Air China has suspended flights to North Korea, further limiting the secretive state's links with the outside world, in what the government said was a business decision with no political motives.
China, the North's sole ally, rejected the new sanctions as "wrong" on Wednesday.
North Korea has criticized the US for relisting the country as a state sponsor of terrorism.
Critics have pointed out the US decision will further escalate tensions between the two countries after Trump, on Monday, put the country back on the list, saying, "Should have happened a long time ago. Again this is all part of us continuing to turn this pressure up".
U.S. Secretary of State Rex Tillerson said the U.S. had expressed its willingness to negotiate with North Korea but had yet to receive a response from the North.
Sudan announced last week that it would end trade and military ties with North Korea, while Egypt, Uganda, Philippines, Mexico, Peru, Kuwait and Spain expelled North Korean diplomats in September following the country's sixth nuclear test.
One Year Later, Uber Comes Clean On Hack Affecting 57 Million People
Amy Spitalnick, spokeswoman for Attorney General Eric Schneiderman, confirmed the probe Wednesday, but would not comment further. Earlier in January this year, Uber was fined US$20,000 for failing to disclose a comparatively less serious breach in 2014.
Major League Baseball drops hammer on Braves' scandal: prospect loss, lifetime ban
The Braves also lost scout Gordon Blakeley, who was removed from the club and subsequently banned for a year. All 13 players will become free agents and are eligible to sign with any team.
Palestinians freeze ties with US
Closing the PLO office may have been a strong-arm tactic to force the Palestinians to the negotiating table. The declaration does not automatically mean the mission will close.
But North Korea is unlikely to give in to the sanctions and come back to the negotiation table anytime soon. One of his favorite comments is the US should have re-designated North Korea as a sponsor of terror "a long time ago" - that was a dig against Obama's policy of "strategic patience" in dealing with the North.
European researchers say they have identified the targets North Korea is planning to attack. He and Trump appeared to have gotten along quite well during Trump's recent visit - an occasion for him to call for strengthening South Korea's armed forces. North Korean leaders and state media have said North Korea will not negotiate its nuclear program.
The UN estimated the latest ban, imposed after its two intercontinental ballistic missile tests in July, would slash by North Korea's $3-billion annual export revenue by a third.
USA diplomats responsible for negotiating with the North Koreans in previous years were by and large supportive of strong sanctions - and also of calling North Korea a "terror state".
Whatever the actual U.S. intentions on the matter, putting North Korea back on the terror list accomplishes nothing, but risks damaging diplomacy.
US officials cited the killing of North Korean leader Kim Jong Un's estranged half-brother in a Malaysian airport earlier this year as an act of terrorism.
