63-year-old Singh, who was appointed Minister for DONER with independent charges, said that he "strongly condemns" the harassment of the people from the North East.
"It will be my priority to find a solution to this," he tweeted this evening.
Singh, who will take charge of his ministry tomorrow, was elected to Lok Sabha from Ghaziabad constituency in the recent general elections.
Singh also thanked everyone for their wishes and blessings, saying it will be his constant endeavour to deliver on the promises and to live up to people's expectations.
