The three countries agreed that : Both Belgium and the Netherlands had commercial treaties which contained the most-favoured-nation clause with for instance the United Kingdom and other countries . The Ouchy Convention contained a clause that it should not come into effect until these countries had waived their rights . At the British Empire Economic Conference at Ottawa of July – August 1932 the United Kingdom opposed the Dutch – Belgian interpretation of the most-favoured nation clause of the Ouchy convention . The refusal of the United Kingdom to waive its rights as most-favoured nation and the fact that the United States made no reply to the request for a waiver , made the convention fail without ever coming into operation
