Secretary of State George P. Shultz said Saturday he is confident that pressure from the Soviet Union and China will deter North Korea from staging terrorist attacks at the Olympic Games.

Shultz, on the seventh stop of a nine-nation Asian tour, also reaffirmed Washington's commitment to the security of South Korea."I think everybody will be exerting their influence in a positive way. I feel that the Olympics will go off in good style," Shultz told reporters shortly before landing in the South Korean capital after leaving Beijing.

On the eve of Shultz's arrival, the United Nations Command accused North Korea of trying to undermine the Olympics by making war threats and "contriving tensions."

"Your attempts to contrive an atmosphere of danger on the Korean Peninsula, in a transparent attempt to undermine the upcoming Seoul Olympics, will not succeed," said U.S. Rear Adm. William T. Pendley, chief UNC delegate to the Military Armistice Commission.

Olympic security is one of the issues Shultz is expected to discuss when he meets President Roh Tae-woo and other government and opposition leaders this week. U.S.-South Korean trade and America's continuing military role in South Korea also are slated for discussion.

Shultz said that in preparing for the Olympics, the South Koreans were alert to the placing of surface-to-air missiles within range of Seoul.
