SHANGHAI, March 30 (Reuters) - China stocks surged to seven-year highs on Monday on hopes that more infrastructure spending and policy stimulus will re-energise the cooling economy and boost corporate profits.
The CSI300 index of the largest listed companies in Shanghai and Shenzhen rose 2.9 percent, to 4,088.18 points, while the Shanghai Composite Index gained 2.6 percent, to 3,786.57 points.
Infrastructure-related shares climbed 5.6 percent after Beijing unveiled details of an ambitious plan to improve links from Asia to Europe and Africa.
The project, a network of railways, highways and other infrastructure, would create a new Silk Road that President Xi Jinping said would in a decade generate $2.5 trillion in annual trade with the countries involved.
Shares were also supported by dovish comments from central bank Governor Zhou Xiaochuan at the weekend that reinforced expectations for further monetary easing to support the slowing economy.
In addition, investor enthusiasm got a boost from a commentary in Monday's People's Daily saying China's bull market can aid the country's economic restructuring. The article from the Communist Party's mouthpiece added to signs that policymakers support the stock market's rise, despite some analysts' concerns that prices have run up too much, too fast.
Among the most active stocks in Shanghai were China State Construction, up 10.0 percent to 7.94 yuan; Bank Of China, up 3.2 percent to 4.46 yuan; and Agricultural Bank Of China, up 2.8 percent to 3.74 yuan.
