Carnival Corporation has announced that Buhdy Bok has been promoted to the new position of president of Carnival Asia.

He will report to Michael Thamm, group CEO, Costa Group and Carnival Asia.

In his new role, effective May 1, Bok will have responsibility for expanding Carnival Corporation’s growth and scale in Asia, supporting the company’s global development initiatives. He will relocate from Shanghai to Singapore, where he will work from the company’s Carnival Asia headquarters. Bok previously served as president of Costa Group Asia.

“Buhdy Bok’s promotion to this newly created position underscores how valuable his leadership and contributions have been in helping build Costa Cruises’ leading presence in China and Asia, while also recognizing the importance of the entire Asia region to Carnival Corporation,” said Thamm, who oversees the Costa Group, which consists of Germany-based AIDA Cruises and Italy-based Costa Cruises, and all operations for Carnival Corporation in Asia.

Bok joined Costa Cruises in May 2011 as vice president China and received several promotions before being named president of Costa Group Asia in October 2015. Under his leadership Costa grew the Asian business exponentially and developed China as the number one source market for Costa Cruises.

Carnival Corporation also announced that Mario Zanetti, currently senior vice president of revenue management & itinerary planning for Costa Cruises, has been promoted to president of Carnival China effective on May 1, reporting to Thamm. Zanetti has held various key positions with Costa Cruises over the last two decades and completed his executive education by attending general management programs at Insead Business School. While taking over his new position, he will relocate to Shanghai.

With these appointments, Roger Chen continues as chairman in China for Carnival Corporation with responsibility for growth and industry development initiatives in the expanding Chinese market. Based in Shanghai, Chen will continue reporting to Thamm.
