British Prime Minister David Cameron has said the United Kingdom will support India’s membership to the Nuclear Suppliers’ Group. His assurance to Prime Minister Narendra Modi over a phone call on Thursday comes a week before the monitoring body’s plenary meeting in Seoul on June 24.

“The prime minister confirmed that the UK would firmly support India’s application. They agreed that for the bid to be successful, it would be important for India to continue to strengthen its non-proliferation credentials, including by reinforcing the separation between civil and military nuclear activity,” a Downing Street spokesperson said, according to PTI.

The NSG is an international group comprising 48 countries that work together to monitor and control the export of materials or technology that can be used to create nuclear weapons. India has applied for membership to the group in May.

Besides the UK, India’s bid to be part of the NSG has the support of the United States and Switzerland. However, the move has drawn opposition from Pakistan and China, which is leading a group of countries that is against India’s membership to the group. These include New Zealand, Austria, South Africa, Ireland and Turkey.
