On 23 June 1970, Baron Hubert Ansiaux, Governor of the National Bank of Belgium, Chairman of the Committee of Governors of the Central Banks of the EEC Member States and member of the Werner Committee, writes to his friend Robert Triffin, a Professor at Berkeley College and close associate of Jean Monnet on the Action Committee for the United States of Europe, to inform him and to ask for his support on the question of making progress in the monetary field without prior convergence of economic policies, given the hostility of the German and Dutch representatives in the discussions of the Werner Committee.
