I would say the challenge is adaptation.
We have to adapt ourselves to the new reality of China, and we also have to adapt to the reality of China itself. That's to say that the world has changed, and not just in China. The United States has changed in response to it. We have to adapt to this world. Our traditional policies haven't worked and aren't working. We can't simply rely on our ally to protect us, because our ally has turned its back, in some ways, on the rules-based international order.
We saw in fact that the January 15 agreement is a managed trade agreement. The United States will now be playing a role in which they take unilateral gains from their relationship with China based on their market size, not on the rules-based order. We actually have to work to protect the rules-based order, and our best partner may not be the United States. This is a new world.
