London (CNN) -- The BRIC nations were the ones tagged to drag the globe out of economic despair. But, as the world struggles to recover from the credit boom and bust, they too are stumbling.
Ahead of the St. Petersburg International Economic Forum June 20 to June 22, CNN is hosting a tweet chat with authors and representatives from Google, the United Nations and the Organisation for Economic Cooperation and Development to debate which economies might emerge strongest out of the financial crisis.
The tweet chat will take place on June 18, 1500CET/1400 BST/1300 GMT using the hastag #emergeCNN.

The discussion will center around the BRICs and their claim to be the world's future powerhouses. We will discuss if they still deserve to hold that title as they slump while other markets show resilience.
China, the globe's second largest economy, was tipped to overtake the U.S. as the world's economic leader by 2016, but its growth outlook has been downgraded by forecasters including the International Monetary Fund.
The IMF pointed to the country's rapid expansion in credit, which some analysts worry is reaching a growth-sapping scale.
The ease of credit is also raising concerns in Brazil, and there is a debate over whether it even deserves to be a BRIC nation. Brazil grew by less than 1% in 2012, the lowest of the BRIC countries.
In the West, the U.S. and Europe are emerging from the crisis at two speeds: Slow in the U.S., but even slower in Europe.
Meanwhile focus is turning to economic brights lights elsewhere in the world. Sub-Saharan Africa's economy, for one, is expected to grow by 5.6% this year, well ahead of the global average.
At the forum, John Defterios will discuss the potential for other emerging players such as Indonesia and Vietnam.
So which economies will emerge from the crisis as winners, and which will be left behind? Join our chat to have your say.
