European leaders are calling on the U.S. to be sure and steer clear of the "fiscal cliff" coming at the end of the year, for the good of the global economy.

While European nations are grappling with a debt crisis on their own continent, European Commision President Jose Manuel Barroso and European Council President Herman Van Rompuy are also concerned about fiscal struggles afflicting other nations, in particular the United States and Japan.

In a letter sent to all members of the European Union, the two called for the others to adopt "credible medium-term fiscal consolidation plans." The letter came in advance of a June meeting of the G20 powers in Mexico.

"Whilst we are firmly focused on playing our part, at Los Cabos all other G20 partners should also recognise their responsibilities in building a sustainable recovery," they wrote. "In this regard, the EU should urge the US and Japan to implement credible medium-term fiscal consolidation plans, in particular to avoid the 'fiscal cliff' in the US at the end of the year."

U.S. lawmakers have been consistently warned about the extreme policy swings set to take effect at the end of the year, as the Bush-era tax rates expire and automatic spending cuts stemming from the summer's debt limit deal take effect.

Federal Reserve Chairman Ben Bernanke has called on Congress to replace those laws with more gradual fiscal tightening, and the Congressional Budget Office said earlier this month that the economy would dip into a recession with changes.

In their letter, the European officials argued that Europe is focused on producing a "comprehensive response" to its debt crisis, and that they want Greece to remain in the eurozone while addressing its fiscal woes. They added that Europe should press China to boost its safety nets and allow the financial markets to set the exchange rate on its currency.
