I'd say it's a combination of yes and no. Nazi Germany's racial policies against East Asians were a mixed bag between contempt and ambivalence. Although Hitler and Himmler admired East Asian culture, they were still ranked below the so-called Aryans. They were still subject to racial laws and anti-miscegenation laws, just not as strictly as say, Jews or other Eastern Europeans.

Chiang Wei-Kuo was an interesting case as his enlistment in the Wehrmacht represented the height of Sino-German cooperation shortly before Hitler went all out on supporting the Japanese. Since Chiang was an ideological ally at the time (both he and Hitler were fiercely anti-communist), it is most likely that he would be treated as an equal as a Wehrmacht soldier and citizen for the sake of international integrity. If Chiang tried to, say, marry a German woman or apply for German citizenship, the Nazis would have put up lots of bureaucratic roadblocks to make sure it didn't happen at all. By accounts of his time in the Kriegsschule, he was an excellent cadet and served with distinction as a panzer commander just before graduating and being recalled in 1939. Otherwise, he would have taken part in the Invasion of Poland. In Chiang's later years, he expressed gratitude to Germany for training him and even wrote a letter in November 1970 to Erich Stoelzner, a former military adviser to the KMT in the 1930s.
