Nissan Motor Co. is accelerating the rollout of electric vehicles in China under its main brand and its local, no-frills Venucia marque as it overhauls its strategy in the world's biggest auto market, four sources have told Reuters.

Besides the focus on green vehicles, the plan involves using more locally made parts and technologies to reduce costs and help the struggling Japanese carmaker compete better with lower-cost Chinese firms and major global rivals, the sources said.

The China strategy is a key pillar of Nissan's turnaround, which involves focusing on producing profitable cars for China, Japan and the United States, rather than chasing all-out global growth as it did under disgraced former boss Carlos Ghosn.
