On 21 March 1978, the Secretary-General of Western European Union (WEU) circulates the final reply by the WEU Council to Assembly Recommendation 310 on the spread of nuclear energy and defence problems. The Council emphasises that the member governments of the WEU Council are promoting cooperation on controlling the peaceful use of nuclear energy between nuclear technology supplier countries, but it also notes that the International Atomic Energy Agency (IAEA) is responsible for controlling all sensitive exports to non-nuclear weapon states. With regard to the protection of nuclear facilities and nuclear materials, the Council points out that each state must make its own arrangements for the implementation of such protection, although studies on various international protection measures are also under examination within the IAEA.
