UNITED NATIONS, April 15 (Reuters) - The United States and Japan on Wednesday delivered to a U.N. sanctions committee lists of North Korean companies they want placed on a U.N. blacklist for aiding Pyongyang's nuclear and missile programs.

"We have received communications from two countries, the United States and Japan," Turkish U.N. Ambassador Baki Ilkin, chairman of the U.N. Sanctions Committee on North Korea, told reporters after the committee met behind closed doors.

It was the first meeting in two years of the committee, which so far has not designated any company to be blacklisted. As a result, financial sanctions and an arms embargo imposed on Pyongyang after it carried out an October 2006 nuclear test have not been enforced.

Ilkin gave no details of the lists provided by Washington and Tokyo. But one U.N. diplomat told Reuters the U.S. list had 11 companies linked to the North Korean military on it.

Another diplomat said the types of goods that North Korea would be banned from importing and exporting would be those found on sensitive technology lists drawn up by the Missile Technology Control Regime and Nuclear Suppliers Group, informal clubs of countries interested in halting proliferation.
