Eurozone: How could China's help ease the debt crisis?

The head of Europe's bail-out fund Klaus Regling is in Beijing, trying to persuade China's government to help ease the eurozone debt crisis.

Eurozone leaders want to expand the European Financial Stability Fund to one trillion euros, to continue to support indebted governments in the eurozone.

It is looking to raise much of the cash from fast-growing, cash-rich emerging economies like China.

The BBC's Jeremy Howell explains how the scheme would work.
