If their goal was a bait-and-switch then why change the title? If you're trying to con someone out of information why make the victim aware of your intentions right before the con? It is possible that they thought "US China AI Summit" would be a little alienating so to get some initial sign-ups they put out something softer, but that just seems like a marketing decision. When I hear "Building Across Borders" my first thought is "Oh, it's an international conference. Let's see which countries will be there! Oh look it's a ton of Chinese people...", not really concealing anything beyond the superficial. I have no love of the Chinese government, but this is a free exchange of ideas that is open to the public (for a $40 ticket). Given the actions of the Chinese government to date, if this is how they plan to get more technical data going into the future I'm hoping they do more of this and less hacking of proprietary/classified info. :P
