It's going to be a roller coaster ride

International and domestic companies are rushing to invest in China's amusement parks, but analysts have warned of fierce competition and low profits.

Six Flags theme parks, a US company, and Riverside Investment Group, a real estate developer in China, have formed a partnership to build a number of Six Flags-branded theme parks in China over the next decade. Terms of the arrangement were not disclosed.

Texas-based Six Flags Entertainment Corp, with $1.1 billion in revenue, has 18 parks across the United States, Mexico and Canada.
