VIENNA, July 3 (Xinhua) -- Progress has been made on nuclear disarmament regarding efforts made by the United States and Russia in the past two years, a U.S. official said here on Wednesday.
"We disagree with the states that claim there is no progress on disarmament," Thomas Countryman, U.S. assistant secretary for international security and nonproliferation, told reporters at the International Conference on Nuclear Security.
He said the United States and Russia have made efforts to boost the nuclear disarmament in the past 50 years, especially the past two years.
"We will continue to move forward," he said.
Nuclear disarmament is supposed to be a tough issue in the international community. Some states claim no progress has been made on this issue in recent years, and suggest that some super nuclear powers should reduce their nuclear arsenal first.
Organized by the International Atomic Energy Agency (IAEA), the International Conference on Nuclear Security is being held in Vienna on July 1-5.
The conference aims to strengthen global efforts to enhance understanding of current approaches to nuclear security and identify trends, and to provide a global forum for ministers, policymakers and senior officials to formulate views on the future directions and priorities for nuclear security.
