It's easy to say close the HK border with China, but there's a couple of significant points.
Firstly, a lot of fresh food, and I use the term 'fresh' with a degree of caution, come from the mainland, which can lead to food shortages in HK. And secondly, we need to be mindful of which large Capital City north of here that makes the REAL decisions about such things.
I'm not saying the border doesn't need shutting, it does to people, and should have been done last week.
