From the Hindustan Times, this Reuters article recorded Lamy's remarks that he made while in the UK.
The Doha round was launched in late 2001 to boost world trade and help developing countries export their way out of poverty, but agreement has proved elusive.
The G20 group of rich and emerging nations called in November for an outline deal by the end of 2008 to help counter the economic crisis.
But last month Lamy decided political differences were still to wide to invite ministers to Geneva to seek a breakthrough.
In his speech on Thursday he praised Britain's support for the negotiations and Prime Minister Gordon Brown's leadership.
"It is this leadership that we are counting on to ensure that the coming G20 summit in April here in London will result in a recommitment to conclude the negotiations this year," said Lamy, who also met Brown on Thursday.
Lamy said the crisis made it more urgent to reform the global trading system to help developing countries.
"There is no doubt that this crisis will have profound and possibly prolonged effects on developing countries, the least developed among them in particular, whose recent good economic performance has been largely driven by external factors," he said.
