Alibaba's (BABA) AliExpress said Monday it has launched its new AliExpressLocal Marketplace model and advanced integration tools in the US.

The new model provides US merchants with maximum autonomy, allowing more flexibility in determining the pricing, marketing, and merchandising of their products, the company said.

The company also introduced two application types, AliExpress Open API and Third-Party Software Vendor, which enable software-as-a-service platforms to integrate directly with AliExpress.

Shares of Alibaba were up 4.6% in recent trading.
