At 0820 GMT, the euro zone benchmark (STOXX50E) was up 0.4 percent with most European bourses and sectors trading in positive territory.
"News overnight of a late agreement between the U.S. and Canada to salvage the NAFTA trade agreement should give a boost to global risk appetite at the start of the fourth quarter," wrote Peel Hunt strategist Ian Williams, adding the deal "may offer encouragement that the other global trade disputes can settled satisfactorily."
