The remarks made in the presence of Commerce Minister Faruk Khan were criticised here and New Age in an editorial called the envoy's behaviour 'arrogant'.
New Age in an editorial Friday asked Dhaka to 'uphold dignity of the country and its people' and warned that 'New Delhi needs to realise that, in Chakravarty, it may have a loose cannon ball that, if not immediately reined in, could cause irreparable damage to India's relations with Bangladesh'.
Chakravarty is already in the midst of another controversy for terming the critics of Tipaimukh dam that India proposes to build over Barak river in Manipur state as 'so-called experts'.
Mahmud's observation came as Bangladesh prepares to send a team of parliamentarians, officials and a water resource expert to visit the dam site next week.
Addressing the business meet, Prime Minister Sheikh Hasina said there was no issue between the two South Asian neighbours that could not be resolved through talks.
