International issues are quite complex and require consideration of various factors.
Leaving other aspects aside for now, just in terms of economics, there are some things that, with my current technology, I can't produce, or the cost is high, or production is low. For example, sugar, rice, rubber... and on your side, they are dirt cheap.
Might as well buy them, since they're so cheap.
Coincidentally, I also have some things that I can produce but can't use up, like tung oil, bristles, and silk. The domestic market can't digest them, so productivity can't improve.
If we don't sell them and they just pile up in warehouses, it's a pure loss.
That's why free trade is advocated.
Whether Tushan is weird or not is not something the country needs to consider.
High-quality talents from the United Kingdom, advanced science and technology, and resources and markets from overseas colonies are what the country needs to consider.
