Fox News says North Korea has boosted its production of opium and heroin in a bid to secure foreign currency.

The report said that after seeing satellite photos of the camp released last week by Amnesty International, analysts noted the that poppy fields around the Yodok camp had expanded by 130-thousand square meters since 2001.

Chuck Downs, executive director of the Committee for Human Rights in North Korea, said that the growth of the farmland is the result of the bite of trade sanctions that are beginning to devastate the nation's economy and the need to quickly replace the hard currency lost to sanctions.
