China emerged from the weekend Group of 20 meeting with a new measure of trust from major trading partners that it won't significantly devalue the yuan. Persuading investors might be tougher.

Chinese Premier Li Keqiang and central bank chief Zhou Xiaochuan worked hard to dispel worries among visiting G-20 finance ministers and central bankers that their economic strategy hinges on weakening the yuan's exchange rate.

The message was "heard loud and clear" that Beijing has "no intent, no determination, no decision whatsoever to devalue the yuan," said Christine Lagarde, the managing director of the International Monetary Fund, after the weekend meetings in Shanghai.
