In initial trade, London's benchmark FTSE 100 index of major blue-chip firms jumped almost 0.6 percent at 7,110.11 points.
In the eurozone, the Paris CAC 40 index won 0.5 percent to 4,988.09 and Frankfurt's DAX 30 climbed 0.5 percent to 10,955.83 points, compared with Friday's closing levels.
Global stocks had mostly fallen on Friday at the end of a tumultuous week that was dented by worries over slowing global growth and continued uncertainty on US-China trade talks.
However, Asian equities saw gains Monday as US and Chinese officials in Beijing geared up for crunch trade talks aimed at averting fresh tariff escalations.
