* U.S.-China trade disputes weigh on economic growth outlook
* Saudi Arabia crude output down 400,000 bpd in Jan -OPEC sources

SINGAPORE, Feb 8 (Reuters) - Oil markets were cautious early on Friday, held back by concerns over a global economic slowdown but supported by supply cuts led by producer club OPEC and U.S. sanctions against Venezuela.
U.S. West Texas Intermediate (WTI) crude futures were at $52.61 per barrel at 0046 GMT, down 3 cents from their last settlement. WTI dropped by around 2.5 percent the previous session.
International Brent crude oil futures had yet to trade.
Weighing on financial markets, including crude oil futures, were concerns that trade disputes between the United States and China would remain unresolved, denting global economic growth prospects.
U.S. President Donald Trump said on Thursday he did not plan to meet with Chinese President Xi Jinping before a March 1 deadline set by the two countries to achieve a trade deal.
If there is no agreement between the world’s two biggest economies, Trump has threatened to increase U.S. tariffs on Chinese imports. Another round of talks is scheduled for next week in Beijing.
“Crude prices returned to the lows of the week as slower growth prospects...could signal a return (of reasons) for inventories to rise,” said Edward Moya, market analyst at futures brokerage Oanda.
Despite this, traders said crude prices were prevented from falling much further by supply cuts led by the Organization of the Petroleum Exporting Countries (OPEC), which were introduced late last year and are aimed at tightening the market and propping up prices.
As part of these cuts, Saudi Arabia - the world’s biggest crude oil exporter and de-facto leader of OPEC - cut its crude output in January by about 400,000 barrels per day (bpd) to 10.24 million bpd, according to OPEC sources.
Another risk to oil supply comes from Venezuela after the implementation of U.S. sanctions against the OPEC-member’s petroleum industry in late January. Analysts expect this move to knock out 300,000-500,000 bpd of exports.
Yet for the time being, the sanctions impact on international oil markets was limited.
“The (Venezuela) disruption overall seems manageable both for the U.S. and the global market,” said Norbert Rücker, head of commodity research at Swiss bank Julius Baer. “The oil market sits on a comfortable cushion of supply.” (Reporting by Henning Gloystein Editing by Kenneth Maxwell)
