A 'one-trick pony'?
Simon Littlewood, president at business advisory firm ACG Global told the BBC there were concerns that the world's second biggest economy was "a one-trick pony as they have been trying repeatedly over the past few months to put more liquidity into their economy", yet so far have failed to calm markets.
Over the past week, China's benchmark Shanghai Composite fell 12%, adding up to a 30% drop since the middle of June.
The sharp fall sparked a global sell-off, with the Dow Jones in the US losing 6%, while the UK's FTSE 100 posted its biggest weekly loss this year of 5%.
Earlier this month, the Chinese central bank devalued the yuan in an attempt to boost exports.
