The companies will set up a joint venture to feature Marriott's entire line-up, from the eponymous brand to the Sheraton and Ritz-Carlton, on Alibaba's Fliggy site.

Meanwhile, Marriott said in a news release, "The joint venture will leverage Marriott International's global portfolio of brands and unparalleled hospitality expertise to revolutionise the travel experience as well as Alibaba's digital retail leadership and its role as a gateway for worldwide brands to reach over 500 million mobile monthly active users across its platforms".

Tourists will be able to pay for bookings using the Chinese e-commerce company's online payments platform, Alipay, the companies said.
For Marriott, the partnership puts the brand in front the 500 million Chinese mobile users who are active across Alibaba's platforms. Last week, Alibaba and Ant unveiled a wide-ranging cooperation agreement with Cathay Pacific Airways Ltd. "Both of us believe we can generate huge synergies from this strategic partnership".
Marriott's hoping to widen its slice of that market.
"We are proud to join forces with Marriott International - combining our large-scale consumer base, leading edge technology and consumer insights with their unparalleled hospitality expertise", said Alibaba Group CEO Daniel Zhang in the statement.
