Does made in Mexico mean made by China?

I had a job once making plastic handles for garden hose sprayer nozzles, we had cheap aluminum Chinese made hose nozzles that we plastic molded a handle around that said "made in USA" proudly on the side and completely covered the "made in China" stamped into the metal.
This was legal because the handle was indeed made in the USA, but it was advertised on the packaging in a way that implied the whole thing was made in the USA when it reality it was just the plastic grip.
