Beijing ? North Korea insisted Wednesday it should get a nuclear reactor to generate electricity in exchange for abandoning atomic weapons development, but the main U.S. envoy at disarmament talks said Washington and its partners have no intention of meeting the demand.

After his first one-on-one meeting with the North Korean delegation at this round of six-nation talks on the communist nation’s nuclear program, U.S. Assistant Secretary of State Christopher Hill said the sides “did not make a lot of progress.”

The talks resumed Tuesday after a five-week recess, and also include China, Japan, Russia and South Korea.

Under the offer on the table, North Korea would receive economic aid and security guarantees from Washington along with free electricity from South Korea for dismantling its nuclear weapons program.

But the Pyongyang regime has also asked for a light-water nuclear reactor, a type believed to be more difficult to be diverted for weapons use.
