China has accused the United States of exaggerating Russia's military buildup and creating instability in Ukraine's society and economy in the process.

"Such persistent hyping up and disinformation by some Western countries will create turbulence and uncertainty to the world full of challenges, and intensify distress and division," Chinese foreign ministry spokesman Wang Wenbin told reporters at a regular briefing in Beijing on Wednesday.

"We hope relevant parties will stop such disinformation campaigns and do more to benefit peace, mutual trust and cooperation.The leadership of the two heads of state, China and Russia, always work to develop long term good neighbourliness and mutually beneficial cooperative relationship on the basis of non-alliance, non-confrontation and non-targeting of third countries," spokesman Wang added.
