This, he said, would help to promote national integration. Sangma was virtually participating at the NITI Aayog Governing Council meeting where Arunachal Chief Minister Pema Khandu had also made a similar suggestion. "In the @NITIAayog Governing Council meeting chaired by @narendramodi ji, honble CM Arunachal Pradesh @PemaKhanduBJP ji gave a wonderful suggestion of including more info on north east culture chapters in national syllabus. It will go a long way in building national integration," the chief minister tweeted. Sangma also stressed the importance of strengthening cooperative federalism. "In #NitiAayog's Governing Council meet with PM @narendramodi ji, Lt Governors & CMs, stressed on the need to strengthen cooperative federalism through Sister-State relationship & the role GoI can play in fostering reciprocal economic development for States," he added.
