China is a good example. When the work started with China in the 1990s we were paying for the Chinese to come to us. We were paying their expenses when they came and spent time here for training. When we do work with China, they pay their own way and we pay our own way.
The last couple of times I've gone to China to do lectures at their schools, they've wanted to pay me for doing that. I have enormous trouble accepting money as a public servant, so I don't accept any of that money. But there is a willingness to pay for things to be done if they really need it, and they certainly pay their own expenses.
