HANGZHOU - With the rapid expansion of China's e-commerce sector, courier companies have shifted up a gear as they pursue overseas expansion.

During a forum on courier services held last week in east China's Zhejiang Province, Yu Weijiao, chair of Shanghai-based YT Express, said in the following two to three years, China's courier companies will expand overseas, benefiting both Chinese and international customers.

YT Express ordered 15 Boeing 737 jets from the United States in September to sharpen its competitiveness.

Chen Dejun, chair of Shanghai-based STO Express, said STO had set up 12 transit centers and over 100 branches in the United States during the past two years.

The annual business volume of Chinese courier services is already the best in the world, and the development of cross-border e-commerce companies will further boost the industry's overseas business, he said.

Statistics show that China's courier companies delivered 14 billion packages in 2014, and 15.6 billion have been delivered during the first ten months this year, up by 46 percent annually.
