Circumstances where masks will help:

If you are sick and want to protect others (this is the primary reason why China suggests it)
If you are caring for someone who is sick, but only if you use other protective equipment (gloves) and know how to use it (you are correctly fitted and you are used to avoiding touching your face after coming into contact with potentially contaminated people or surfaces, which is much harder than it sounds.
I have seen lots of people reach under their mask to scratch an itch around their mouth, which completely negates any benefit from the mask.
