(Reuters) - U.S. stocks trimmed earlier strong gains in afternoon trading on Thursday after Wall Street found relief in Beijing's efforts to halt a rout in Chinese stocks, which lifted markets around the world.
Wall Street had fallen sharply in the previous session as market turmoil in China, a rout in commodity prices, the Greek debt crisis and a major outage on the New York Stock Exchange spooked investors.
China's securities regulator, in its most drastic step yet to arrest a selloff on Chinese stock markets, banned shareholders with large stakes in listed firms from selling for the next six months.
About 30 percent has been knocked off the value of Chinese shares since mid-June. Some investors fear that the turmoil in the Chinese market could destabilise the global financial system, making it a bigger risk than the Greek crisis.
Adding to cautious optimism on Wall Street, European markets rose on hopes that Greece might be able to win a deal that could keep it in the euro zone. Greek Prime Minister Alexis Tsipras has until midnight to propose spending-cut plans.
"There a relief that (China's selloff) didn't continue. There's a relief that there doesn't seem to be any belligerent tone coming out of Greece," said Steve Goldman, principal of Goldman Management in Short Hills, New Jersey.
At 2:25 p.m. (1825 GMT) the Dow Jones industrial average <.DJI> was up 44.39 points, or 0.25 percent, at 17,559.81. The S&P 500 <.SPX> was up 6.19 points, or 0.3 percent, at 2,052.87 and the Nasdaq Composite <.IXIC> was up 19.75 points, or 0.4 percent, at 4,929.51.

Seven of the 10 major S&P 500 sectors were higher, with the financial index <.SPSY> leading the gainers with a 0.67 percent rise.
The NYSE, which accounted for about 13 percent of the volume of U.S. stocks traded last month, said Wednesday's halt was due to a technical problem that stemmed from new software rolled out the previous evening.
U.S. second-quarter earnings season is getting under way with major U.S. banks scheduled to report next week.
