WASHINGTON (AFP) - US President Barack Obama on Wednesday certified that India has placed safeguards on its nuclear facilities, taking another step toward full implementation of a landmark cooperation deal. In a memorandum, Obama confirmed that India has formally agreed to provide access to the UN nuclear watchdog, the International Atomic Energy Agency (IAEA), of its civilian nuclear reactors. Obamas certification clears another hurdle for the agreement to come into force, but more steps remain. It shows continued progress and gives reason for optimism that final implementation issues can be resolved soon, said Ted Jones, a director at the US-India Business Council who follows the energy industry. US businesses have complained that despite the promise of the nuclear agreement, they still cannot seal deals in the growing Indian market without resolution of remaining issues.
