NEW YORK, Feb 9 (Reuters) - U.S. stocks slipped on Monday, on the heels of disappointing Chinese economic data and increased tensions over Greek debt negotiations, though the decline was limited by another gain in oil prices.
China's exports fell 3.3 percent from a year ago while imports tumbled 19.9 percent, well short of expectations, raising concerns about the health of the world's second-largest economy.
"China is a negative and Greece is a negative, certainly Greece is something investors have lived with for a while and it's not a huge surprise," said Rick Meckler, president of investment firm LibertyView Capital Management in Jersey City, New Jersey.
Greece's Prime Minister Alexis Tsipras ruled out any extension of its international bailout on Sunday and announced moves to reverse some of the reforms imposed by its lenders. On Monday, European Commission President Jean-Claude Juncker said Greeks should not expect the euro zone to accept the latest terms proposed by Greece.
