Tokio Marine Holdings Inc., fresh from its biggest acquisition in the U.S., is now looking for opportunities in China.

The insurer plans to utilize its ties with Citic Group Corp., China's biggest conglomerate, to expand in the country, Tsuyoshi Nagano, Tokio Marine's president and chief executive officer, said in a recent interview in Tokyo. The company last year invested 780 million Hong Kong dollars (¥12.5 billion) in Citic Ltd., the Hong Kong-listed arm of Citic Group.

"We are currently considering ways to expand in China," said Nagano. "With Citic, we would like to jointly invest in good companies and then start insurance businesses together."
