The United States has expressed hope that its National Security Agency's surveillance on the BJP would not have an adverse impact on its bilateral ties with India.

State Department Spokesperson Jen Psaki told this to reporters yesterday when asked about the strong protest lodged by India against the spying of BJP by the NSA.

Psaki said, Washington looks forward to continuing discussion with New Delhi on a full range of bilateral and regional issues.

On the possible September visit to the US by Prime Minister Narendra Modi, she said, there has been an invitation issued for a visit, and US is looking forward to that.
