PERTH, Nov 16 (Reuters) - Oil prices clawed back some of last week's 1.4 percent losses on Monday to rise above $77 a barrel, supported by a weaker U.S. dollar and improved risk appetite.

Positive data from Japan, the world's third-largest energy consumer, whose economy expanded 1.2 percent in the third quarter from the previous three months, also lent support to oil prices.

U.S crude futures for December delivery CLc1 rose 70 cents to $77.05 a barrel by 0315 GMT. The contract touched a one-month low and settled 59 cents lower at $76.35 a barrel on Friday.

London Brent crude LCOc1 gained 59 cents to $76.90.

"Oil prices are up mostly because of U.S. dollar weakness. The market is expecting the dollar to fall lower this week," said Jonathan Kornafel, Asia director at Hudson Capital Energy in Singapore.
