India, a founding member of the Non-Aligned Movement (NAM), was not invited to a luncheon meeting hosted by US vice president Joe Biden, where he professed that the grouping and his country had similar goals on nuclear security and non-proliferation.

Only those member states of the NAM which are part of the Nuclear non-Proliferation Treaty (NPT) were invited to the luncheon hosted by Biden at his official residence on the margins of the Nuclear Security Summit here, a senior White House official said.

Since India is not a signatory to the NPT, it was left out, the official told PTI.
