I've learned over my 30-plus years of driving to be very careful about the blind spot behind my right shoulder because the mirrors I usually rely on don't show me everything. So I always swivel and check before changing lanes.
A couple of weeks ago, one of New Zealand's most experienced and successful business leaders, Sir Henry van der Heyden, forgot to check New Zealand's biggest blind spot before commenting.
His now famous comments about "never, ever" trusting businesspeople in China sparked quite a storm. He quickly apologised and put it in the appropriate context of Fonterra's misplaced trust in its joint venture partner Sanlu.
But the intensity of the reaction threw a spotlight on a vulnerability in New Zealand's current economic strategy. Just like the blind spot for a driver; we all know it's there, but we hardly ever talk about it. And just like the truck that seems to appear out of nowhere as we move into the next lane, China is looming very quickly up behind our economy.
New Zealand is betting its economic future on a country with which we have few durable cultural or political ties. We don't know its history, we don't understand its political system and we don't really know how it "works". This has happened much, much more quickly than the previous shifts in our economic and strategic landscapes. China has jumped from being our third-biggest partner to our biggest in less than five years.
