Taiwan's Maritime and Port Bureau has banned 267 vessels from entering its territorial 

waters and ports from June 5, in accordance with the UN North Korea sanctions resolu

tion, according to a port circular issued Tuesday. 

"These sanctions are for all countries... it is coming from the UN. Some Taiwanese did 

business with North Korean ships... and their assets were [seized]," said a shipping exe

cutive from a North Asian refiner. 

Of the 267 vessels, four were registered as container liners and the rest are a mix of 

dry bulk and wet tankers. 

The UN Security Council passed Resolution 2371 on August 5, 2017, with the approval

 of all five permanent members and 10 non-permanent members -- its sixth sanction on 

the Democratic People's Republic of Korea -- in response to the country's persistence 

with nuclear tests. 

The sanction includes barring North Korea from the supply, sale and transfer of commod

ities including coal, iron, iron ore, lead and lead ore, as well as seafood. 

It also restricts North Korea's access to the international financial system and prohibits 

other nations from hiring any more North Korean workers. 

North Asian market participants Wednesday said most countries and companies in the 

region no longer actively deal with North Korean vessels as a result of the sanctions. 

"The point is who chartered the vessel, as they are the one doing the illegal business 

-- the vessel owner may not have intended to smuggle or do illegal things," the source 

said, adding "if ships are caught, [authorities] will use a satellite or drone to take a phot

o of the ship; they will take evidence". 

The resolution excludes oil refined products of up to 500,000 barrels until December 31, 

2020.
