She was scheduled to attend the Commonwealth heads of government meeting (CHOGM) from Nov 25 to Nov 29 in Malta and the climate summit beginning Nov 29.
PMO and foreign ministry officials confirmed to bdnews24.com the latest developments.
Commonwealth heads of government will convene in Malta before the Paris gathering.
But officials in Dhaka have given no specific reason as to why the prime minister decided to skip the summit where some 120 heads of state and government are expected to gather on Nov 30.
They would only say that the decision had been taken considering the overall situation at home and in Europe.
War criminals Salauddin Quader Chowdhury and Ali Ahsan Mohammad Mujahid are expected to be executed anytime soon as the legal battle regarding their activities during the War of Liberation has drawn to an end.
They can now seek presidential clemency.
The Prime Minister had earlier called off her Paris tour slated for Nov 16 following the terrorist attacks that left about 130 people dead in the French capital.
She was scheduled to attend the Unesco 'Leaders' Forum' there.
Paris is still reeling from the attacks. It has cancelled civil societies’ rallies during the climate summit on security grounds.
