* Escalating Syria crisis lifts crude to highest since late 2014
* Trade dispute between U.S. and China also keeps market on edge
* U.S. production hits fresh high of 10.53 million bpd
* U.S. crude inventories rise to 428.64 million barrels
* Shanghai crude futures trade record volumes since launch (Adds comment, updates prices)
SINGAPORE, April 12 (Reuters) - Oil markets remained tense on Thursday on concerns over a military escalation in Syria, although prices remained some way off Wednesday's highest since late 2014 as bulging American supplies weighed.
Ongoing trade disputes between the United States and China also kept markets on edge, traders said.
Brent crude futures were at $72.14 per barrel at 0536 GMT, up 8 cents, or 0.1 percent from their last close.
U.S. WTI crude futures were at $67.03 a barrel, up 21 cents, or 0.3 percent from their last settlement.
In China, Shanghai crude futures were also up, rising 8.9 yuan to 427.1 yuan ($68.03) per barrel, up 2.1 percent and with record volumes traded on the product that was only launched in late March.
Both Brent and WTI hit their highest since late 2014 of $73.09 and $67.45 per barrel on Wednesday, respectively, after Saudi Arabia said it intercepted missiles over Riyadh and U.S. President Donald Trump warned Russia of imminent military action in Syria.
"Geopolitical risks outweighed an unexpected rise in inventories in the U.S.," ANZ bank said on Thursday.
Ongoing concerns of a prolonged trade dispute between the United States and China are also keeping markets on edge.
China lashed out at the United States on Thursday saying that the trade disputes, in which both sides have threatened to impose tariffs on imports of several products, were "single-handedly provoked by the U.S." and that Beijing was prepared to escalate the spat if Washington did not back off from its threatened import tariffs.
The Chinese Commerce Ministry also said there had been no bilateral negotiations with the United States on the trade frictions.
Although markets are tense, supplies remain ample especially due to the United States.
U.S. crude oil inventories <C-STK-T-EIA> rose by 3.3 million barrels to 428.64 million barrels.
Meanwhile, U.S. crude oil production <C-OUT-T-EIA> last week hit a fresh record of 10.53 million barrels per day (bpd), up by a quarter since mid-2016.
The United States now produces more crude than top exporter Saudi Arabia. Only Russia, at currently just under 11 million bpd, pumps out more.
"Barring any geopolitical shocks, we see limited upside potential for oil prices from current levels due to ongoing oversupply, mainly from the U.S. and Russia, and also a slowing demand growth outlook," said Georgi Slavov, head of research at commodities brokerage Marex Spectron.
