"It is very unfortunate to learn about such discrimination and segregation of the northeast people," Sazo said.
The authorities had ordered workers of the hotel from the northeast region "not to come for work" during Jinping's stay.
The Speaker also regretted the alleged exclusion of Union Minister of State for Home Kiren Rijiju's name from the list of delegation to meet the Chinese president.
"East, West, South or North we are all Indians. Our colours may be different but we should stand for unity in diversity," Sazo said.
The Home Ministry yesterday directed the Intelligence Bureau to find out the veracity of the hotel authorities' 'order' and, if so, who issued it and why.
Earlier, Assam Chief Minister Tarun Gogoi had said, "It is an insult to the northeast. They doubted us as if we are not patriots. Are we not citizens of India? This is not good for the region.
