Environmentalists have been criticizing big developing nations for blocking plans for efficiency standards on shipping.

The talks in Tianjin are meant to lay the groundwork for the main Climate Change conference to take place in Mexico later this year.

Joining me now is Iruthisham Adam, the Maldives' Ambassador to UN office in Geneva. She is also leading the Maldives delegation at the Tianjin talks.
