the machinery used to process (heavy metals transferring to leaf) along with extraneous pollutants in the processing facility itself can taint a tea especially if it is chopped and cut to a greater degree (factories are only as clean as the people cleaning them...and some people are not conscious/don't care of how pollutants can enter into the steps of processing/the facility).
That is just a small picture though imo. So much rides on the EXACT environmental conditions of where it was grown, how balanced it was with the surroundings, and how its energies balance with the individual drinkers energy/thought. Then there's transportation/handling, storage issues etc etc.
To go back to your original question, I think there is some truth in what you have been hearing (but by "chinese teas" I am referring to loose leaf tea grown well). But don't automatically assume because it is loose leaf that is is good quality. And vis versa for tea bags (esp the ones from overseas).
