China accelerated the opening of its capital markets by more than doubling the amount foreigners can invest in stocks, bonds and bank deposits as the government shifts its growth model to domestic consumption from exports.

The China Securities Regulatory Commission increased the quotas for qualified foreign institutional investors to $80 billion from $30 billion, according to a statement on its website yesterday. Offshore investors will also be allowed to pump an extra 50 billion yuan ($7.95 billion) of local currency into the country, up from 20 billion yuan.

China, the world's second-biggest economy, has pledged this year to free up control of the yuan and liberalize interest rates as the government deepens reforms to revive growth and offset slowing exports and a cooling housing market. China needs to rely more on markets and the private sector as its export- oriented model isn't sustainable, World Bank President Robert Zoellick said in February.
