US investor Warren Buffett says there won't be a recession if Congress can't resolve the so-called fiscal cliff before the automatic tax increases and spending cuts take effect in January.

Buffett told CNN on Wednesday that the US economy is very resilient, and it won't collapse if President Barack Obama can't immediately broker a plan.

The billionaire's view differs with economists who have predicted a recession is likely if the fiscal cliff isn't addressed.

Buffett told CNN: "We are not going to permanently cripple ourselves just because 535 people can't get along."
