A partnership between PayPal (NASDAQ:EBAY) and leading Chinese e-commerce platform DHGate.com has unraveled: DHGate, which claims to have over 3M buyers and 20M product listings, says it no longer accepts PayPal as a payment method, due to mutual disagreements. The deal was PayPal's biggest in China, whose online payments market is dominated by Alibaba (OTC:ALBCF), Tencent (OTCPK:TCEHY), and China UnionPay.
