“SeaWorld’s future is brighter than it was two days ago,” said Dennis Spiegel, president of the International Theme Park Services trade group. “You already have Disney in China as well as Universal; now you have SeaWorld.”

The deal should close in the second quarter of this year and the deal was worth about US$429 million.

The world’s most populous country and second-largest economy has been a popular target for theme-park companies in recent years. Disneyland Shanghai opened in June and Universal is working on a park near Beijing in partnership with several state-owned companies. There are more than 100 theme park-projects in the works in China from both Chinese and foreign investors, Spiegel said.

China has 39 marine mammal parks, including massive attractions such as the Chimelong Ocean Kingdom near Hong Kong.

Zhonghong’s other theme-park developments include the Monkey Kingdom theme park being built outside Beijing. Monkey Kingdom is based on a 16th-century Chinese novel “Journey to the West” and is expected to include roller coasters, boat rides and more.

Hailed as a “Disney-quality” concept, Monkey Kingdom was supposed to open in 2014 on 100 acres at a cost of US$1.5 billion under Zhonghong’s real estate arm.

Zhonghong’s deal says that SeaWorld will “advise on the concept development and design of theme parks, water parks, and family entertainment centres to be developed and operated by Zhonghong Holding, including exclusive rights in China, Taiwan, Hong Kong and Macau.”

“China has invested enormously in its leisure industries in recent years and this gives Zhonghong both a partner with deep knowledge in the business and access to SeaWorld’s well-known brands,” theme-park analyst Bob Boyd of Pacific Management Group said in an email.

Possible theme parks in China are part of a growing global strategy for SeaWorld. In December the company announced that it was partnering on a new theme park in the United Arab Emirates. That park is slated to open by 2022.

Friday’s agreement contains restrictions on Zhonghong’s ability to sell its interest in SeaWorld for a period of two years. It also cannot acquire more than 24.9 per cent of SeaWorld’s outstanding shares without the approval of the independent directors of SeaWorld’s board.

Following the closing, Blackstone and its affiliates will no longer hold any interests in SeaWorld or have seats on the board of directors. Blackstone first bought SeaWorld in 2009, then took the company public in 2013.

Blackstone bought the company just a few months before an orca killed trainer Dawn Brancheau at the company’s Orlando theme park. That set in motion a chain of events that included the 2013 documentary “Blackfish,” which brought arguments against captivity into the mainstream. SeaWorld has suffered for several years now from declining attendance and revenue, and much of that has stemmed from controversy over its orcas.

Blackstone used to hold a stake in Universal Orlando.

SeaWorld CEO Joel Manby said in a news release: “Zhonghong Group has a strong track record of performance in the leisure and travel industries, and a solid management team with valuable experience in theme parks, family entertainment, and real estate development in Asia.”

One of SeaWorld’s two new board members is theme park and entertainment veteran Yoshikazu Maruyama, the head of Zhonghong’s American operations and a former executive at DreamWorks and Universal.

The other new board member is Yongli Wang, Zhonghong’s chief strategy officer who has held several spots in the international banking and finance industry.
