China has spent more than US$50 billion ($60.2 billion) in the past three months on energy and infrastructure deals in central Asia.
Chinese outbound investment totalled just over US$100 billion in the third quarter of 2013 with around half of that sum spent in the central Asian states visited by the Chinese President Xi Jinping on an official tour last month.
"Investment closely tracks where the [Beijing] Government turns up," said Henry Tillman, the chief executive of the merchant bank Grisons Peak which compiled the figures. "We've not noticed such a strong correlation before."
Xi visited Turkmenistan, Kazakhstan, Uzbekistan and Kyrgyzstan in September and signed sizeable business deals with all four countries. The pattern of spending confirms that Chinese foreign investment flows are largely determined by the political leadership.
"Everyone thinks that's the case. But those are the numbers," said Tillman.
