Canada is interested in joining the trade pact after a blow last week to its proposed Keystone XL pipe line expansion-- the US State Department decided to delay allowing the expansion of TransCanada's Keystone XL pipeline in order to study alternative routes. As a result, Canada is now shifting focus to Asian nations as a potential location for energy exports.
Japan's inclusion in the pact may face opposition from its local government and citizens, as concern grows over the removal of tariffs on some of Japan's most-exported goods, such as cars and rice.
