The Trump Administration is seeking to deepen its counter-terrorism cooperation with India and expand it further, sources in Washington said after National Security Advisor Ajit Doval's meetings with top US officials. Mr. Doval during his US visit this week met Defense Secretary, Gen (Rtd) James Mattis, Secretary of Homeland Security Gen (Rtd) John Kelly, and National Security Advisor Lt Gen H R McMaster. <br/><br/>Expansion and deepening of India-US co-operation in collectively addressing the challenge posed by terrorism in South Asia was the common agenda in all these meetings. Pentagon Spokesperson Capt Jeff Davis said Defense Secretary Mattis specifically applauded India's efforts to promote stability in the South Asia region and both leaders reaffirmed building upon the significant defence cooperation progress made in recent years. This was Doval's second trip to the US after Trump won the presidential elections in November.
