It seems Johnson has raised the question whether New Zealand is closer to China than Wales. That is be no means as straightforward as you might think. By air it may well be closer. But the most likely common product in which Wales and New Zealand compete is lamb, and that is typically sent by ship, not air. Which means the ships either have to go through the Panama, which is expensive, or round South America, which is expensive and takes a long time. Either puts Wales at a competitive disadvantage.
