Those two are inseparable. China's policy towards foreign media is a domestic policy. Diplomacy and trade relations are subservient to that. They are worried about foreign influence on chinese political culture. That is what is being mirrored in the US by the tiktok case.
In any case, the has never been symmetry... or any intention to have symmetry. Each country has its goals. That's how trade deals always work.
China's primary goals were/are exports and the abovementioned protection against foreign and/or free media. The US' goals are US investment into china, an american-like legal framework for protecting these investments and adoption of US-compatible IP protections. That's what each side wanted. It reflects values. That's what they got. Both complain they didn't get enough of what they wanted.
It's not like the US is going to adopt elements of chinese patent law for the sake of symmetry.
