China has announced new measures aiming at sustaining its economic growth. These include plans to build railways, roads and airports along the Yangtze River--which connects China' s less developed inland provinces to Shanghai. Meanwhile, China' s central bank said it will encourage banks to lend more to exporters to boost shipments. The moves, the latest in a series of steps taken in recent weeks, come amid concerns over a slowdown in China' s economy-the world's second-largest. China's economy expanded by 7.4% in the January-to-March period, from a year ago, down from 7.7% growth in the final quarter of last year. After years of robust expansion, China has seen its growth rate slow in recent years, in part due to a slowdown in demand for its exports from key markets.
In an attempt to sustain a high growth rate, and to rebalance its economy, China has been looking to boost domestic consumption. However, there have been concerns that as China tries to move away from an export-led growth model, growth may slow down further. On Wednesday, the State Council said that the decision to build a multitier transport system along the Yangtze River will help create a new economic belt along the river. "Better use of the so-called 'golden waterway' can boost economic integration between developed and impoverished regions and inject fresh energy into China' s economic growth," the State Cabinet was quoted as saying by the state-owned Xinhua news agency.
