LONDON - Brazilian President Luiz Inacio Lula da Silva met Queen Elizabeth II Thursday on the last day of his trip to Britain, where he sought to drum up investment and signed an Olympic cooperation deal.

The meeting at Buckingham Palace followed talks Wednesday with Prime Minister Gordon Brown, who penned a government-to-government agreement with Lula to share business expertise between the two Olympic host nations.

It will allow organisers of the 2016 Games in Rio to learn from London's experience of hosting the 2012 Olympics, including on how to deliver a legacy that benefits the whole country.

"As this is the first time a South American country will host the summer Olympics, this agreement will establish a structured cooperation programme which will allow the UK and Brazil to share knowledge and experience," a spokesman for Brown's Downing Street office said.

The two leaders also discussed climate change ahead of a major UN-sponsored meeting in Copenhagen in December where nations will try to hammer out a new accord to succeed the Kyoto Protocol on curbing greenhouse gas emissions.

Lula met with business leaders earlier Thursday to urge them to invest in Brazil, saying it was a country with "enormous challenges" but huge opportunity.

Brazil officially emerged from recession in the second quarter of this year -- unlike Britain, where the downturn continues -- and is expecting full-year GDP growth of between 0.1 and 1.0 percent.

The government is aiming to boost investment to help achieve five- to six-percent growth in the next few years.

Later Thursday, Lula was to receive an award from the prestigious Chatham House think-tank for making "the most significant contribution to the improvement of international relations" over the past year.

He will be feted at a gala dinner before flying home at the end of his two-day visit, officials said.
