SEOUL, Jan. 16 (Yonhap) -- The top U.S. diplomat on East Asian policy, Kurt Campbell, warned North Korea on Wednesday against taking "provocative steps" amid concerns Pyongyang may conduct a nuclear test following last month's rocket launch.

When asked about the North's potential third nuclear test, Campbell replied, "We are very clear in our position that provocative steps are to be discouraged."

  


Campbell arrived in South Korea on Tuesday with other senior officials from the White House and the Pentagon, marking the first high-profile visit by U.S. officials to Seoul since President-elect Park Geun-hye's election victory last month.
