Beijing - Shares on China's two stock markets gained more than 3 per cent for a second successive day on Friday, amid continuing expectation that the government plans more measures to bolster the economy.

The key Shanghai Composite Index, which tracks shares traded in foreign and local currencies, surged by 3.05 per cent to close at 1,986.44 points, up 58.82 points.

The smaller Shenzhen Composite Index jumped by 4.4 per cent, or 22.76 points, to end the day at 545.34.

The Shanghai index took its total gains this week to nearly 14 per cent, buoyed on Friday by the overnight surge on Wall Street.

Nearly all stocks on the two markets rose, led by real estate and energy firms, with combined turnover reaching 127.9 billion yuan (18.8 billion dollars), the Shanghai Daily newspaper reported.

The markets were driven by the "strong expectation" that the central bank will lower its base interest rate over the weekend, the newspaper said.

Analysts said investor confidence was also boosted this week by speculation that the government would introduce more measures to promote economic growth, after the announcement Sunday of a package that included 4 trillion yuan (586 billion dollars) for infrastructure projects over the next two years.
