China's central bank has eased rules regarding overseas investment in the country's interbank market.

A notice issued on late Tuesday suggests foreign central banks, sovereign wealth funds and global financial organizations could have easier access to China's interbank bond market.

Under the new rule, a pre-approval to trade bonds, interest-rate swaps and conduct repurchase agreements will no longer be needed.

These institutional investors are only required to fill in a registration form with the central bank before investing in the interbank market.

They will also be free to decide on the size of their investment.

The easing policy comes as China aims to promote globalization of the yuan currency to support its inclusion into the International Monetary Fund's basket of reserve currencies.
