S Korean nuclear envoy arrives in Beijing

---

BEIJING, Mar 24 (AP): South Korea's top nuclear negotiator arrived in Beijing Tuesday for talks aimed at reviving efforts to verify North Korea's nuclear programmes amid growing unease over Pyongyang's plans to launch a rocket.
Wi Sung-lac was scheduled to meet with Chinese Vice Foreign Minister Wu Dawei Tuesday and Wednesday before heading to Washington for further discussions.
Wi told reporters at the Beijing airport that key topics are "the missile problem and the nuclear six-party talks" but did not elaborate.
The flurry of activity comes amid concerns about North Korea's declaration that it will fire a rocket in early April in violation of a UN ban prohibiting the country from ballistic activity. Some fear the launch is a cover for the test-fire of long-range missile technology.
