WASHINGTON - US President Donald Trump ordered a widening of US sanctions on North Korea on Thursday (Sept 21) in an effort to further constrict its trade with the outside world.

Here's a quick look at some of the details:

1. The US government will freeze the funds of any entity that does any kind of business with North Korea.

This includes:

- entities who own, control, or operate any port in North Korea, including any seaport, airport, or land port of entry

- anyone who has engaged in at least one significant importation from or exportation to North Korea of any goods, services, or technology

- any North Korean person, including a North Korean person that has engaged in commercial activity that generates revenue for the Government of North Korea or the Workers' Party of Korea.

2. The order essentially covers a wide range of industries.

From construction, energy, fishing and financial services, to information technology, manufacturing, medical, mining, textiles, transportation, and operation of any port of entry on land and sea.

3. No ship or aircraft can visit the US within 180 days of going to North Korea.

The same restriction would apply to any vessel involvement in ship-to-ship transfers with North Korean vessels.

4. Banks doing business in North Korea will not be allowed to also operate in the United States.
