Oil prices fell on Monday amid renewed global economic growth concerns after U.S. President Donald Trump vowed to escalate the trade war with China with more tariffs, which would likely limit fuel demand in the world's two biggest crude consumers.

Brent crude futures LCOc1 fell 73 cents, or 1.2%, to $61.16 a barrel by 0458 GMT, Reuters said.

U.S. West Texas Intermediate (WTI) crude futures CLc1 dropped 62 cents, or 1.1%, to $55.04 a barrel.

Both crude benchmarks fell last week, with Brent dropping 2.5% and U.S. crude falling 1%.

Trump last week said he would impose a 10% tariff on $300 billion of Chinese imports starting on Sept. 1 and said he could raise duties further if China's President Xi Jinping failed to move more quickly towards a trade deal.

The announcement extends U.S. tariffs to nearly all imported Chinese products. China on Friday vowed to fight back against Trump's decision, a move that ended a month-long trade truce.

On Monday, China let the yuan tumble beyond the key 7-per-dollar level for the first time in more than a decade, in a sign Beijing may tolerate further currency weakness because of the trade dispute.

The 1.4% drop in the yuan came after the People's Bank of China (PBOC) set the daily mid-point of the currency's trading band at its weakest level since December 2018.

A lower yuan would raise the cost of China's dollar-denominated oil imports. It is the world's biggest crude oil importer.

Signs of rising oil exports from the United States also pressured prices on Monday. U.S. shipments surged by 260,000 barrels per day (bpd) in June to a monthly record of 3.16 million bpd, U.S. Census Bureau showed on Friday.
