North Korea is a difficult country to visit, but there are tours that are offered. Some people go and will actually have an opportunity to visit North Korea as a tourist.
There are other groups that visit, a number of NGOs. There are American NGOs and Canadian NGOs that provide humanitarian assistance and that visit North Korea. They are allowed to visit hospitals and medical facilities, where they provide assistance and advice.
There is a very interesting university called the Pyongyang University of Science and Technology, PUST. It is an organization funded largely by South Korean and Korean-American and other groups that provides instruction in science and technology and business in English. The faculty is largely composed of people who volunteer. The groups involved in this are primarily Christian groups. There are people who go and instruct in mathematics and in science and in business topics. They are one of the universities in North Korea that functions in North Korea. The student body is selected by the North Korean government, but all of the instruction is in English and the teachers there are teaching them topics that you'd teach in a Canadian or American university.
So there is some effort in terms of people going into North Korea, and I think these are all positive. It's seen by North Koreans as being positive because they need information in these areas.
