SOVIET ‘NYET’: London, 25 – A meeting of experts due to convene in Geneva, Switzerland, on July 1 to find ways to monitor a halt to thermonuclear tests has been canceled following the sudden withdrawal of the Soviets. After US Secretary of State John Foster Dulles said on June 17 that the meeting would be useful irrespective of any decision it may reach to halt testing, Soviet Foreign Minister Andrei Gromyko sent a message to the US ambassador in Moscow that his country would not be participating, as Dulles’s statement negated the purpose of the meeting. Gromyko’s statement surprised Washington, where President Dwight D. Eisenhower called Dulles in for a meeting. The Soviet withdrawal, considered to be without reason, is being attributed to domestic pressure related to the position of Prime Minister Nikita Khrushchev.
