GUANGZHOU: The successful Guangdong International Tourism and Culture Festival has become a perfect stage to showcase the popularity of Guangdong and Pan Pearl River Delta (PPRD) region as a tourism destination, said Tang Bingquan, vice-governor of Guangdong Province.

According to the provincial tourism administration of Guangdong, more than 40,000 people attended the opening ceremony of the festival. More than 1, 000 high-ranking officials from the central government and Guangdong provincial government, World Tourism Organization, consulates (领事馆) of various countries in Guangzhou, and other provinces of China, also showed up in the ceremony. The activities in the past few days attracted a large number of visitors from home and abroad.

In the past 30 years, Guangdong Province has been one of the leaders in the nation in terms of economic development. Its average annual economic growth maintained a rate of 13.8 percent, according to Tang.
