U.K. theme-park operator Merlin Entertainments Plc is eyeing a potential deal with SeaWorld Entertainment Inc., in a bid to expand its overseas presence, Bloomberg News reported, citing people with knowledge of the matter.

Merlin Entertainments has approached SeaWorld to buy part of the U.S. theme-park giant. However, according to the sources, SeaWorld would prefer a complete sale. Other companies have also shown interest in SeaWorld, which has hired advisers to explore various options including a sale, according to the Oct. 4 report.

Merlin runs Legoland parks globally and runs the Thorpe Park Resort in England.

Earlier this year, China's Zhonghong Zhuoye Group Co. Ltd. acquired about 21% stake in SeaWorld for $23.00 per share from certain funds affiliated with Blackstone Group LP.
