Wall Street JournalWASHINGTON -- Signs of growth in North Korea's nuclear program and the country's increasing isolation are renewing fears about Pyongyang's ability and need to smuggle weapons of mass destruction around the world, said U.S. and United Nations officials.
North Korea's arms trade has focused on Iran and Syria, countries Washington views as state sponsors of terrorism, as well as Libya. Officials say North Korean arms have also been sold to nations allied with the U.S., such as Egypt and Pakistan, and to the military regime in Myanmar.
The concerns about North Korean weapons proliferation were heightened this week with Pyongyang's underground test of a nuclear weapon and several short-range missile launches. Sales of short- and medium-range missile systems remain among North Korea's largest export earners, part of an arms trade that generates $1.5 billion annually for Pyongyang, say North Korea analysts.
With the international community looking to punish the regime for the nuclear test, U.S. and U.N. officials say Pyongyang could try to increase exports of its nuclear and missile technologies as it gradually loses its ability to obtain hard currency from foreign aid and exports to markets such as Japan and South Korea.
