BEIJING, Aug 2 (Reuters) - Trafigura's top crude oil marketer in China, Geng Tao, said on Thursday he has left the Swiss commodities trading house, the latest sign that business in the world's largest crude importer is getting more challenging.
In a phone call, he said he departed the company a few days ago.
Trafigura declined to comment.
His exit comes after the company appointed Ben Luckock and Robert Gillon as co-heads of oil last month.
