They will present their ideas at global summit in the US capital on November 15.
Twenty of the world's richest nations and biggest emerging economies will gather in Washington DC to discuss the ideas including on how to prevent a similar crisis happening again.
Sarkozy, George Bush, the outgoing US president, and Jose Manuel Barroso, the European Commission president, agreed last month to hold a number of summits on the issue.
With France holding the current EU presidency, it will be Sarkozy's role to present the European bloc's case.
Friday's meeting in the Belgian capital appears to have overcome divisions within the EU on how much regulation the financial system should be subjected to in the future.
Jonah Hull, Al Jazeera's correspondent in Brussels, said that Britain and France favoured a high degree of regulation, but that Germany was worried that this would hamper individual countries facing recession.
Currency change
Analysts had predicted before the conference that some EU countries which had previously opted out of the euro would contemplate switching to it to bring stability.
Adhip Chaudhuri, an economics professor at the Georgetown University's Doha campus, said: "There is speculation that some non-euro countries, like Denmark and Sweden, may switch to the euro currency.
"After the Iceland experience, these two countries have seen the collective strength of the European currency, whereas we saw Iceland struggling alone."

European markets

Oil dropped briefly below $60 a barrel before bouncing back to nearly $62 and the dollar was generally weaker.
Franz Wenzel, a strategist at AXA Investment Managers in Paris, said: "This is simply a technical rebound, nothing else, because valuation wise, earnings and everything is still fairly bleak.
"There is no fundamental reason other than maybe people starting thinking about monetary policy in a more positive sense and commodity prices are giving some support."
