Opposition insists there was a "serious lapse" and breach of protocol during the visit of Bangladesh's deputy minister in-charge of cultural affairs Promod Mankin, who was the guest of honour in the closing ceremony of Hundred Drums Wangala Festival last month.
The opposition also demands an apology from the government.
Replying to this in the Assembly, state minister in-charge of general administration department (GAD) Prestone Tynsong said, "Due courtesies and protocol was provided" to the guest.
Mankin, the lone Garo Member of Parliament in Bangladesh, had led a troupe of around 30 Garo drummers and dancers from his country to join their ethnic siblings in Meghalaya to celebrate the annual jamboree from November 11 to 16.
