SINGAPORE, Dec 20 (Reuters) - Oil prices inched higher on Tuesday, supported by a softer dollar and a U.S. plan to restock petroleum reserves, but gains were capped by uncertainty over the impact of rising COVID-19 cases in top oil importer China.
U.S. West Texas Intermediate (WTI) crude futures rose 32 cents, or 0.4%, to $75.51 a barrel, after climbing 90 cents in the previous session.
Oil prices have been buoyed by a U.S. plan announced last week to buy up to 3 million barrels of oil for the Strategic Petroleum Reserve following this year's record release of 180 million barrels from the stock.
A weaker greenback has also supported prices, making oil cheaper for those holding other currencies.
U.S. crude oil stocks were expected to have dropped last week by about 200,000 barrels, while gasoline and distillates inventories were seen higher, a preliminary Reuters poll showed on Monday.
