This week, Cnooc announced plans to reduce capital spending as the government and large state-owned enterprises respond to the collapse in oil prices. China’s third-largest oil producer said it would cut development spending by 67 per cent and, albeit less dramatically, reduce exploration and production capital expenditure.

At the same time, the Beijing government and refiners such as Zhuhai Zhenrong have increased their purchases of crude oil to record levels. Sinopec, another big state-owned energy enterprise, opened up a tank farm for crude oil on the resort island of Hainan in November.

These apparently contradictory signals reflect changes in the sources of growth in a slowing Chinese economy and show how the government and corporate China are exploiting the collapse to reduce their longer-term vulnerability to price swings in the volatile energy market.
