In August 2017, the UN Security Council adopted a resolution banning all coal, iron, iron ore and lead imports from North Korea. Pictured here is China's Liaoning Greenland Energy Coal Co. in Dandong, on the border with North Korea.

North Korea is prohibited from opening banks abroad, and UN member states are prohibited from operating financial institutions on Pyongyang's behalf. Any dealings that might help North Korea skirt the sanctions are banned, and UN member states must expel and repatriate anyone working on the regime's financial behalf.

This North Korean cargo ship found itself boarded for inspection in the Philippines in March 2016 after the United Nations ordered member nations to de-register any vessel owned, operated or crewed on orders from Pyongyang. North Korean ships also cannot fly the flags of other nations to evade sanctions.

Air Koryo, North Korea's national carrier, remains exempt from aviation sanctions and still has scheduled flights to China and Russia, as well as several domestic routes. However, the airline cannot fly to the European Union, which has banned it on safety grounds, and the United States prevents citizens from legally conducting business with the carrier.

In December 2017, a new raft of UN sanctions targeted fuel imports in North Korea, meaning its residents could have difficulties driving the country in Pyeonghwa sedans (pictured above). The sale and transfer of diesel and kerosene are limited while the import of crude oil is capped at 4 million barrels a year.

UN sanctions limit North Korea's diplomats abroad — at the country's Berlin embassy, for example — to only one bank account each. North Korea is also not permitted to own real estate abroad for any purposes other than consular.

It's a safe bet that North Korea's marching military did not learn its moves abroad: UN sanctions ban foreign security forces from training the country's army, police or paramilitary units. The United Nations does permit medical exchanges, but otherwise allow very little assistance of scientific or technical value.

Anyone wanting to own a larger-than-life Kim will have to await the end of North Korea's nuclear program. The UN sanctions currently ban the sale of statues by the nation.

The opening ceremony for the 2018 Winter Games in Pyeongchang was held at the Olympic Stadium, starting with fireworks on a frigid evening in South Korea. While the weather was often too warm in the previous games in Vancouver and Sochi, that should not be a problem this time around.

As is the case with all Olympic hosts, South Korea took the opportunity presented by the opening ceremony to present something of its culture and traditions to the world.

As is the tradition at both the Winter and Summer Olympic Games, Greece, the ancient home of the Olympics, are the first contingent to enter the stadium for the opening ceremony. Alpine skier Sophia Ralli led what is a realtively small Greek continent into the stadium in Pyeongchang.

The dignitaries watched the opening ceremony from their own VIP stand. Bottom left is German International Olympic Committee President Thomas Bach, to his right, South Korean President Moon Jae-in. Germany is represented by President Frank-Walter Steinmeier (top right).

German President Frank-Walter Steinmeier was witness to a little bit of history as Kim Yo Jong, sister of North Korean leader Kim Jong Un shook the hand of South Korean President Moon Jae.

Germany were led into the Olympic stadium by nordic-combined gold medalist from Sochi four years ago, Eric Frenzel. Germany's flagbearer was chosen in part by a popular vote on the internet, as he beat four other nominees.

Ghana has sent an athlete to the Winter Olympic Games for just the second time. Akwasi Frimpong, who will be competing in the Skeleton, carried the flag into the Olympic Stadium. Downhill skier Kwame Nkrumah-Acheampong had previously represented Ghana at the 2010 Vancouver Games. There are also several other Africans competing at the Games, including from South Africa, Nigeria and Eritrea.

The International Olympic Committee has banned Russia from these Winter Games over its alleged state-sponsored doping program. However, 169 carefully screened athletes have been invited to compete under a neutral flag. The "Olympic Athletes from Russia" followed the Olympic flag into the stadium.

Tongan cross-country skier Pita Taufatofua stole the show when he entered the stadium bare-chested, despite sub-zero temperatures. The 34-year-old had caused a stir at the 2016 Rio Games when he oiled himself up and went topless as Tonga's flag-bearer. Taufatofua, who competed in taekwondo in Rio, had originally planned to keep his shirt on in the freezing cold — but obviously changed his mind...

In a gesture of peace, the host South Koreans entered the stadium together with their neighbors from North Korea. The athletes from the bitter rivals marched into the venue under a unified Korean flag.

IOC President Thomas Bach used his short address to thank the Koreans for entering as a united team. He also called on the around 3,000 athletes to "inspire us all to live together in peace and harmony despite all the differences we have." Then he gave way to South Korean President Moon, who declared the Winter Games open.

There was a time when an athlete could simply walk up to the cauldron with a torch and light the Olympic Flame. Now, though, no self-respecting host would allow the Flame to be lit in such a mundane manner. South Korean figure skater Kim Yuna, who won gold in Vancouver and silver in Sochi, lit the fuse, setting off a tower of fire that shot up to the Olympic cauldron — lighting the Olympic Flame.
