Rishi Sunak has also said he hopes to have a meeting with the Chinese president, Xi Jinping, at the G20 summit. Asked if he would have a bilateral with Xi, Sunak told Sky News:

I'm hopeful that I can. As I said, I think it's important that we engage with people to try and tackle some of these shared challenges. And I'm here to talk to people, and that's what I hope is possible.

I'm very clear that China poses a systemic challenge to both our values and our interests, and it represents the single biggest straight threat to our economic security. And that's why it's right that we take the steps that are necessary to protect ourselves against that.

I think our approach to China is one that is very similar to our allies, whether that's America, Australia and Canada, all countries that I'm talking about exactly this issue with while we're here at the G20 summit.

And I think it's an indisputable fact of the global economy that China is a big part of it. And if we want to solve big global challenges like public health, like Russia and Ukraine, fixing the global economy or indeed climate change, it's important to have a dialogue and to engage with China as part of solving those challenges.
