British Prime Minister Gordon Brown said Friday that 2010 would be a make-or-break year to address the five global challenges.

The challenges were cementing the global recovery, halting climate change, fighting terrorism, reducing nuclear proliferation and turning the tide against poverty.

Brown told the foreign press association that 10 important global meetings to be held this year could shape what the world faces in the next decade and would be determining moments for the fortunes of millions and testing moments for the world's commitment and resolution to work together.

"The truth we have learned in the last two years is that global problems cannot be answered by national or even regional solutions alone; global problems need global solutions: because we need more, not less, global cooperation," Brown said.

On the economic front, Brown said it was now the time to take the next steps, to complete the task of rebuilding the global economy and strengthening financial supervision in the coming months -- at the G20 and G8 summits in Canada and in South Korea, and at the spring and annual meetings of the International Monetary Fund and World Bank.

He also called for a fresh collective commitment to fully implement the G20 framework for strong, balanced and sustainable growth, to coordinate more effectively the regulation of world financial systems, and to build a coordinated approach to levies on the banks to deliver a fairer balance between risk and reward.

On climate change, Brown said: "We must implement the Copenhagen Accord. That means fast-start finance for developing countries for the 2010-12 period."

"So I want to announce that, on March 31, we will hold in London the first meeting of the Climate Finance Group, the advisory group on climate financing established by the U.N. Secretary General."

"We must also re-establish negotiations towards an internationally binding global agreement, using the important meetings in Germany and Mexico this year to accelerate this goal," Brown said.

He said Britain must drive towards creating a low-carbon economy and plans would be announced to promote investment in clean energy and in the thousands of new green jobs they would create.

On security, Brown said the challenges were changing, noting that "today we face a new kind of terrorism, climate change and potential conflicts over resources, cyber crime, piracy and global increases in illegal migration."

Britain had continued to increase investment in strong borders and counter-terrorism at home -- from 1 billion pounds (1.6 billion U.S. dollars) a year on domestic counter-terrorism in 2001 to more than 3 billion pounds (4.8 billion dollars) now.

Brown said, "Our priority remains the Afghan-Pakistan border areas. We look forward to the Kabul Conference."

In addition, the prime minister said relevant countries would hold discussions in Washington next month and in New York the month after on nuclear security and proliferation, the fourth challenge.

"Today, we also launch our Nuclear Center of Excellence, through which Britain can lead global efforts to secure the safe global expansion of civil nuclear power," he said. Britain commits to renew the G8 global partnership beyond 2012 with a renewed focus on nuclear and biological security.

On poverty, Brown said, "In New York six months ago, we launched an historic drive to provide free healthcare to the world's poorest and, as a result, millions of women and children will receive free healthcare for the first time."

The September Poverty Summit in New York would be the defining moment in achieving the poverty goals, Brown said.
