NO.
I’ve used this and confirmed it works via blood tests every 3 months(added B12 test to my usual CBC, lipids, etc).
Pure Advantage Vitamin B12 Methylcobalamin spray

Of course I do not trust China. The problem is there are many medicines that are solely coming from China.
Just FYI, my cyanocobalamin is manufactured in India. Sanofi and EUROAPI are suppliers in France. Transo-Pharm, Rochem Internation, Parm-RX in the US. And of course China with Basic Nutrition and Hebei Yuxing Bio-Engineering supply it.
This specific drug is not, fortunately, solely sourced in China. If the point is to use Methyl in place of cyanocobalamin because of where it is produced, I believe in this case that would not be the best reason.
