* Market eyes Greece's vote on tax hikes, spending cuts * China signals doubt inflation target would be met * Gulf oil output unlikely to fall on IEA move * Coming Up: U.S. personal income at 1230 GMT (Adds comments, updates prices) By Florence Tan SINGAPORE, June 27 (Reuters) - Brent slipped below $103 on Monday, sliding 10 percent in the three sessions since the emergency oil stocks release by consumer countries, as the U.S. dollar gained ahead of a vote by Greece to clear unpopular fiscal austerity measures. The market is positioning itself ahead of economic data from the United States that is expected to show slowing growth. Investors are also concerned about China's economy slowing down more sharply than expected after Premier Wen Jiabao signalled for the first time the country would struggle to meet its 4 percent inflation target this year. ICE Brent crude for August dropped $2.43 to $102.69 a barrel by 0719 GMT, after hitting an intraday low of $102.28. U.S. crude CLc1 fell $1.21 to $89.95 a barrel. "You've got oversupply caused by the Saudis pushing more crude into the market and, on top of that, the SPR release," said Tony Nunan, a risk manager at Mitsubishi Corp. "It's hard for crude to go up as an asset play."
