This is a great reset of the US and Taiwan relationship that will allow new rules to get added by the State Department. Best case scenario is that the two democracies grow even closer together and Taiwan finally gets a US embassy or even a military base. Worst case scenario is Biden goes back to the old behavior of placating China.
In any case, this is great timing, as China suffers from internal turmoils in Hong Kong, Beijing (leadership conflicts), Xinjiang and Tibet. And currently is engaging in a conflict with India, Australia, US, UK, Canada. Quad alliance (Japan, India, US, Australia) https://www.aljazeera.com/news/2020/11/25/what-is-the-quad-c... has been pretty active, and Inter-Parliamentary Alliance on China (senior lawmakers in democracies) https://www.bloomberg.com/news/articles/2020-06-05/lawmakers... have recently formed this year.
Taiwan would be a great formal addition to these alliances, as it could act as a land carrier sitting off the coast of China. With its recent effort underway to build homegrown submarines by 2025, it could repel most of the sea threats from China for a long time https://www.forbes.com/sites/davidaxe/2020/12/02/taiwan-is-b....
