There are several different ways in which the world is influencing and touching North Korea on the ground.
From a governmental perspective, the South Korean government is trying to engage through things like trade. There was the Kaesong industrial complex, whereby South Korean companies set up businesses that would employ North Korean labour, thereby hopefully trickling down some of these wages to North Koreans. But one of the challenges with the governmental issue is that it's also very political, so Kaesong closed down. Many of these South Korean businessmen essentially were held hostage by the government because of political tensions between the two countries.
In Canada it's also challenging, because we have the toughest sanctions in the world on North Korea, tougher than South Korea, the United States, or anyone, but Canada has also allowed exceptions for things like humanitarian aid.
There's also a lot of private involvement on the ground in North Korea, with everything from churches that are helping set up universities like the Pyongyang University of Science and Technology to other organizations that provide things like soybeans and soy milk to children in North Korea.
North Korea's changing from within, I believe, through these exposures to the outside world.
