This would take me into areas in which I am not an expert, but I think it's a legitimate question. It's a little bit analogous to the issue of trafficking and those who take advantage of the escapees. It's also analogous to the quite significant and increasing numbers of North Korean workers who go into neighbouring countries to work—and sometimes distant countries, like Gulf countries, to do particular jobs—and get only a small fraction of the money that is paid to the Government of North Korea for the work they perform.
I think you'd have to balance, on the one hand, the desirability of promoting economic improvement in North Korea and, on the other hand, the misuse of those zones of joint activity. That would require quite a lot of consideration before you could begin sanctioning economic development.
On the whole, economic development, as we've found in other countries, such as Cambodia, is often going to be a key to improving the life of ordinary people. To the extent that we can do that, we can save people from starving.
Never forget that in the 1990s, of a population of 24 million, according to our estimates, a million North Koreans starved to death. At the same time, North Korea was expending huge resources, which could have been devoted to their starving population, on nuclear armaments, on a huge army, and on missile-delivery systems.
It's a matter of trying to get them interested in economics rather than armaments. That is the integrated nature of human rights and also of peace and security.
