June 30 (Reuters) - Wall Street was set to open higher on Tuesday, a day after the Dow and the S&P 500 registered their worst session since October, as investors hoped Greece would strike a last-minute deal to avoid an exit from the euro zone.

Greece is hours away from defaulting on a 1.6 billion euro repayment to the International Monetary Fund.

The European Commission made its final push to try to persuade Greek Prime Minister Alexis Tsipras to accept a bailout deal he has rejected before.

"We are looking at some sort of a bounce from yesterday's sharp decline," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.

"This last-minute talk of a deal is basically causing some short covering."

U.S. corporations have limited exposure to Greece, but investors are concerned about the fallout across Europe if the country exits the euro zone.

In Asia, Chinese stocks reversed course to end up 5.5 percent after the government and regulators stepped up efforts to reverse a 20 percent slump in the past few weeks.
