Strong navy protects interests

The three trial runs of China's first aircraft carrier, the refitted Varyag, in 2011 marked a milestone in Chinese navy's development. But they also drew sharp reactions from some countries intent on raising false alarms.

The aircraft carrier and its trial runs reflect the Chinese navy's growing competence in defending the country's sovereignty and maritime interests. With a coastline of 18,000 kilometers, more than 6,500 islands, and about 3 million square kilometers of maritime area, China needs a strong and modern navy to prevent any violation of its territory, sovereignty over the islands and maritime interests in its waters.

China has to protect its interests on the high seas, too. The country became the world's largest exporter in 2009 and imported 63 percent of its iron ore and 55 percent of its crude oil needs in 2010. The safety of China's personnel, assets and shipping lanes is very important for its economy, to guarantee this it needs a strong navy.
