Under this treaty, the two countries also agreed to exchange data and co-operate in matters related to the treaty. For this purpose, treaty envisaged creation of the Permanent Indus Commission, with a commissioner appointed by each country. The Indus Waters Treaty is the only International treaty that has been implemented over the last 60 years with due diligence and sincerity by both India and Pakistan, in spite of many wars fought between the two countries (the treaty was not revoked either by India or Pakistan during the 1965 or the 1971 war).
