The government signed a controversial civilian nuclear cooperation pact with India on Friday, disappointing A-bomb survivors and other opponents of the deal who believe Tokyo has placed economic gain ahead of its stated goal of global nuclear disarmament.

The pact opens up a massive market for Japan's nuclear energy industry, which suffered a huge setback from the March 2011 Fukushima disaster, and falls in line with Prime Minister Shinzo Abe's infrastructure export-focused growth strategy.

But opponents argue that India, which tested nuclear weapons in the 1970s and 1990s, could end up using technology obtained through the pact for military purposes. India is a nonsignatory to the Nuclear Non-Proliferation Treaty.
