Consequently, China's share in global sales has slipped from nearly 35% in 2011 to an expected 15% in 2015. But it continues to be the second-largest global seller after the U.S., which is expected to notch up sales worth $30 billion in 2015.

Even with the new reality of slow economic growth of 7% or less of gross domestic product, which Premier Li Keqiang describes as the "new normal," China is projected to be the biggest user of construction machinery in the coming years.

Off-Highway estimates show that China will have 22% of global demand in 2019 against 20% in North America, 16% in Europe, 9% in Japan and 8% in India in that year.

This may be due in part to efforts in recent years by the Chinese government leaders to sell construction proposals around the world, which are completed by Chinese contractors with Chinese labor. Chinese contractors are known to generally favor Chinese equipment brands.

A recent example of this diplomatic boost to to construction business surfaces as the China Road Engineering Company inked a deal to construct a 36-km long roll road between Ngawi and Kertosono in East Java region of Indonesia. The project will be built in cooperation with the Indonesian ministry of public works and public housing at a cost of $74 million, which will be financed by China.
