Amazon.com Inc (AMZN.O) will start a business loan program for small sellers in the United Kingdom on Tuesday and is looking to launch it this year in seven more countries including China. Amazon Lending, founded in 2012, plans to offer short-term working capital loans in other countries where it operates a third-party, seller-run marketplace business, the head of Amazon Marketplace, Peter Faricy, told Reuters. The countries are Canada, France, Germany, India, Italy, Spain and China, where credit is becoming a key factor in competing for new vendors and grabbing market share.
