I submitted a piece from Physics Today to HN [1] a few days ago. The article describes how the scientific interaction between the US and China helped the Chinese nuclear program.
For the record, I do not think the benefits from such a wide ban is worth the price. IMHO banning Chinese visitors from NASA facilities is a terrible idea. Why make it so wide? I cannot help but think this decision is driven by some desire for "punishment", which is not logical at all.
