Yes, and there was a huge qualitative & quantitative difference in the ways in which the the tests were designed & carried out. The US tests were specifically designed to be at altitudes where all debris would quickly de-orbit due to drag. China, OTOH, blasted one of their weather satellites in a much higher orbit - 528mi up - resulting in far higher counts of of high velocity space junk which will orbit for centuries. It was the worst incident of creation of space junk in history [1]. China has since committed to more responsible practices.
