Huazhu has become the second Chinese company to invest in AccorHotels, Europe's largest hotel group, joining top shareholder Shanghai Jin Jiang International, which has a 12.4 percent stake.

Huazhu, which is also known as China Lodging Group, said alongside its first-quarter results on May 14 that it had made a "strategic investment" of about 4.5 percent in AccorHotels and asked for a board seat.

Huazhu added that its suggestion had been "positively received" by AccorHotels.

Ties between AccorHotels and Huazhu go back to 2014, when they sealed an alliance to expand AccorHotels' presence in the fast-growing Chinese hotel and tourism market. The Chinese group has the master franchise for the Mercure and Ibis hotel brands in mainland China, Taiwan and Mongolia.

Under the arrangement, AccorHotels has also taken a 10.8 percent in Huazhu and a seat at Huazhu's board of directors.
