So far, about 40 percent of bookings in the rapidly growing Chinese market are made for Costa ships, according to the company.

On March 1, Costa Group launched its first 86-day round-the-world cruise for Chinese passengers with the voyage of the Costa Atlantica. And as early as this month, the Costa Serena will be the third Costa vessel offering cruises from China

Last year, Royal Caribbean Cruises Ltd and Ctrip.com International Ltd announced the forming of a strategic partnership through SkySea Cruises, a joint venture which is designed to serve the Chinese cruise market.

The joint venture was "an important strategic move in the company's expansion efforts in the Chinese market", said Richard D. Fain, chairman and chief executive officer of Royal Caribbean Cruises Ltd.

Meanwhile, China is also working on developing more luxury cruise ships. The China State Shipbuilding Corporation announced it would establish a joint venture with US cruise company Carnival Corp to build China's first luxury cruise ship.

Hu Wenming, chairman of CSSC, said the country needs about 50 luxury cruise ships and the number will continue to rise in coming years with the emergence of the middle class.

The Ministry of Transport data show China will become the largest cruise market in the Asia-Pacific region by 2020 with Chinese passenger numbers reaching 4.5 million.

Chinese overseas tourism tops 100 m mark in 2014

In 2014, the number of Chinese tourists traveling abroad increased by 19.5 percent year-on-year to 109 million, topping threshold of 100 million for the first time in history, according to the China National Tourism Administration.

"China has been the world's largest outbound market since 2012," said the Madrid-based United Nations World Tourism Organization.

During the recent Chinese Lunar New Year holiday, 5.18 million Chinese, 10 percent more than in the previous year, took trips to Thailand, Japan, the United States, and countries in Europe where they were not surprised to see Mandarin-speaking staff in shopping malls and Chinese TV programs in hotels.

"Now the whole European industry pays great attention to Chinese tourists' shopping habits and consumption demand," said Yu Jin, the chief operations officer of Caissa Touristic AG in Hamburg.

At 12 of its retail outlets across Europe, London-based McArthurGlen Group launched a series of promotions during the Lunar New Year holiday, advertising in Chinese social media and providing extra discounts at its stores.

In New York, high-end department store Bloomingdale's put up decorations featuring a giant Chinese coin towering above a blanket of red flowers.

In Berlin, the Arkaden shopping mall in Potsdamer Platz cooperated with the China Cultural Center in Berlin to host an exhibition of Chinese handicrafts and art performances.

It was not always like this. Shi Xiang, director of CNTA in Frankfurt, could still remember when Western countries showed a lack of interest in Chinese tourism promotion in the early 1980s.

"It was a one-way road back then," Shi said. "There was only inbound tourism in China. They (Western officials) thought we were appealing to them for customers and money."

"Now it's the opposite," he added. "They welcome the 100 million Chinese tourists who contribute to their economy."

Data from CNTA showed the number of Chinese tourists traveling abroad in 2014 was nearly 13 times the level in 1998.

"Chinese customers have a very strong purchasing power," said Sonja Roessler, the tourism marketing executive of McArthurGlen's Designer Outlet Berlin, adding that the shopping center would analyze how to improve its services for Chinese customers in the future.

"China is a huge market with great potential for Germany, and contributes the fastest growth of tourists from Asia," said Jia Xiaoli, media manager at the German National Tourist Board.
