Dr Singh urged the NSUI members to convey to the people the facts about the achievements of the UPA regime and the "false" claims of the BJP government.
He said that, for instance, Mr Modi's Make in India campaign was nothing but a "carbon copy" of the UPA government's New Manufacturing Policy, under which it had pledged to raise the share of manufacturing in GDP to 25 percent.
He spoke of the UPA government's initiatives in the areas of education, health, urban renewal and so on.
"I could go on...I want to tell you that we have nothing but to be proud of our achievements. You have the responsibility to go to the people at large and explain to them what was our contribution, what done to lift the masses from poverty, ignorance and disease," he said.
Dr Singh said the aspirations of the youth of the country had grown and the new communication technologies had created new expectations. He said former Prime Minister Rajiv Gandhi had ushered India into the modern IT age.
