The analogy is inaccurate. She broke US law and then came to the US. If you break the law in China, for example by calling Tibet (or Hong Kong) a separate state on social media, you should fully expect to be arrested the next time you travel there. Extending further, if instead of China, you travel to a country friendly to China with an extradition treaty (ex. Russia or Nigeria), China is well within its rights to demand your arrest.
