The Congress on Thursday accused the Adani Group of having business links with a Chinese company in all its infrastructure projects in roads, railways, ports and airport sectors, saying it posed a threat to national security. The remarks prompted Law Minister Kiren Rijiju to hit back at the opposition party. Responding to a tweet by Congress leader Jairam Ramesh, Rijiju said, "Do not comment on sensitive matters. The Congress has no moral right to speak about Arunachal Pradesh."
