Like you, I'm opposed to bringing charges against Snowden. But that first statement you quoted is completely reasonable.
The United States is just saying, in fewer words:
> The United States and Hong Kong have a treaty—an agreement under international law. We are confident that our request for Snowden is covered by the treaty. If Hong Kong doesn't uphold its side of the treaty by complying with our request, it will raise questions about their commitment to the rule of law—international law, in particular.
