Tokyo plans to oppose a U.S.-proposed ban on fishing subsidies in the Trans-Pacific Partnership free-trade talks that Japan will join from July, due to the numerous adverse effects it might have on the nation's fishing industry, government sources said Saturday.

If the interdiction is implemented by the 11 current TPP member states, the government will call for its scope to be limited to subsidies that would unquestionably lead to overfishing, as the Japanese fishing industry heavily depends on this source of funding, according to the sources.

The government's position also reflects concern the ban may include subsidies for the construction of ports and other infrastructure, hindering recovery efforts in coastal regions where the 2011 earthquake and tsunami ravaged local fishing industries.
