I can confirm that the Canada-Japan relationship, as well as the multilateral relationship that organization has with Asia-Pacific countries, has served Canada well in encouraging other countries to follow the Canadian example of signing the convention banning anti-personnel mines, which took place in December of last year.
Not all countries will sign the convention.
Not all countries sign international conventions and treaties.
