Sixty-eight posters highlighting the theme of Hong Kong's participation in the World Expo 2010 in Shanghai, eastern China, were put on show Sunday to mark the 250--day countdown to the event, which falls on Aug. 24.

According to the Hong Kong government website on Sunday, the 68posters in the high-traffic Salisbury Road pedestrian subway at Tsim Sha Tsui, Kowloon will help to publicize Hong Kong's participation in the World Expo which will be held between May 1 and Oct. 31, 2010.

The bilingual posters highlight Hong Kong's connectivity locally, nationally and globally -- a major theme of Hong Kong's participation in the event.

The eye-catching posters bring out Hong Kong's special attributes as a city connected by ideas, creativity, technology, cultural diversity and closeness to nature.

Hong Kong's participation in Expo 2010 covers four aspects: building a stand-alone Hong Kong Pavilion; taking part in the Urban Best Practices Area exhibition; a comprehensive online presence; and organizing a range of events and activities before and during the Expo period.

More than 240 countries, regions and international organizations have confirmed their participation in Expo 2010, which is expected to attract 70 million visitors from the Chinese mainland and around the world.
