Uttar Pradesh irrigation minister Shivpal Singh Yadav on Friday turned down an invitation to him and his ministry officials from the US' Johns Hopkins University.
The minister for his decision cited the "humiliation" of his cabinet colleague Mohammad Azam Khan during his visit to Boston.
"There is no point in going to a country where guests are not respected and are humiliated," he said.
Hopkins University invited the minister to share his experiences on flood control and expediting a water sector restructuring project in his state.
Uttar Pradesh chief minister Akhilesh Yadav in April boycotted his lecture at Harvard Business School after Azam Khan was frisked and detained by the homeland security staff at Logan International Airport in Boston.
