In coming to any view of the sale of the Crafar farms to a Chinese-owned company, the national interest must be kept clearly in mind. The national interest lies in seeing all economic assets in the hands of those who will develop them for the best possible return.
The day is past when state ownership is thought capable of finding their most efficient use. These days a free market is considered better at ensuring resources pass into the hands of those who will extract most value from them. The question that must be asked about the Crafar farms sale is whether the purchaser is a state agency or a market participant.
That matters because a market participant is usually willing to sell an asset if a buyer believes it can be developed for better value. A government, foreign or domestic, does not behave in the same way.
A state can hold investments that are not performing for all sorts of "strategic" reasons. That is particularly true of a foreign government holding property in an economy for which it is not responsible.
The Shanghai Pengxin Group, now permitted to buy the Crafar farms, is often said to be backed by the Chinese Government. But in papers released with the decision yesterday, the company is said to be owned by an individual, Zhaobai Jiang, an engineer who founded a real estate construction company in 1988 and is now rated one of the wealthiest people in China.
