India has told the US that it will go by its national interest while dealing with other countries, including with sanctions-hit Russia from whom New Delhi is procuring S 400 missile defence systems. This was conveyed by External Affairs Minister S Jaishankar to his American counterpart Mike Pompeo during an extensive bilateral meeting in New Delhi. "We have many relationships with many countries. Many of them have some standing, they have a history. So, we will do what's in our national interest," said Jaishankar.
