With a long line of trucks and front loaders fully packed in the spacious yard of his company, Lyu Wei, general manager of Heihe Fengtai Engineering Machinery Products Trade Co, has enough reasons to worry about his company's performance in 2015.

A plunge in the value of the rouble has dealt a deadly blow to his company, the majority of whose revenue comes from exporting engineering machinery products to Russia.

"It was a catastrophe for exporters to Russia. The purchasing power of our partners in Russia was completely paralyzed, and nobody can predict what the market will be like in 2015," said Lyu.
