South Korean officials say Burma has agreed to comply with U.N. resolutions aimed at ending North Korea's nuclear and missile programs.

The move was announced Tuesday by a spokesperson for South Korean President Lee Myung-bak, who is finishing up his landmark two-day visit to Burma.

President Thein Sein acknowledged during meetings with Mr. Lee that Burma has made past deals with North Korea for conventional weapons. But he denied any nuclear connections with Pyongyang, an issue that long been of concern to Seoul.

Mr. Lee also met Tuesday with Burmese opposition leader Aung San Suu Kyi, who said South Korea and Burma have much in common in having had to take the hard road to democracy.

“We have to make sure that we do not dissipate this good will and that we put it to the best use possible by making sure that it is used in the best way possible, which is for the sake of our people.”

Mr. Lee is the first South Korean president to visit Burma since 1983, when North Korean commandos attempted to assassinate one of his predecessors in Rangoon.

Amid heavy security, Mr. Lee visited the site of the bombing, which targeted then-President Chun Doo-hwan, but instead killed 21 others.

South Korean officials also said Tuesday Burma has agreed to release a North Korean defector who was serving a five-year prison sentence for illegally entering the country.
