"Ge xia, wo hen huanying nin dao yindu lai - I extend a very warm welcome to you in India," Sushma Swaraj greeted the Chinese president.
Earlier Thursday, Xi was presented a guard of honour at the Rashtrapati Bhavan here. He also visited Rajghat - memorial to Mahatma Gandhi - and laid a wreath.
Prime Minister Narendra Modi and Xi would hold talks at Hyderabad House later in the day.
