It was supposedly to punish China for some trade violation but it was clearly meant to punish American Gun owners.
Those guns were of excellent quality. Maybe very good is closer but they were not junkers by any means. The M1911s quickly obtained a very fine reputation both for the quality of workmanship and the quality of the steel.
I forgot another one. They made a nice M-14 except the early stocks were poorly made. The metal work was fine. I think many people swapped out the stocks for original M-14 plastic ones.
I guess trying to pluck the goose that would hiss the least.
