Trump-Xi Summit: A Win for Trump or Another Beijing Trick?

The Trump-Xi meeting at the G-20 summit last weekend took many people by surprise. Before the summit, most pundits predicted there would be very little outcome. Trump would persist on structural changes and Xi Jinping would refuse. Most likely Beijing will revert to its old tactics of agreeing to something but never really doing it. They would intend to buy their time in order to come up with new ways to maintain the status quo. But this time it felt different. Xi Jinping kicked off the conversation with a 30-45 minute monologue. He detailed a substantial concession list from the Chinese side. It seemed he did everything to prove his commitment before the American hawks. Does he really want to give up what he absolutely wouldn’t before? If so, why the change of heart?
