LONDON: Oil prices rose on Monday after US President Donald Trump imposed tariffs on Canada, Mexico and China, raising fears of supply disruption, though gains were capped by concern over what could be an economically damaging trade war. Brent crude futures rose $1.28, or 1.7 percent, to $76.95 a barrel by 3:32 p.m. Saudi time after touching a high of $77.34. US West Texas Intermediate crude futures were up $1.89, or 2.6 percent, at $74.42 after touching their highest since Jan. 24 at $75.18.
