Early chinese imports are unmarked or marked with chinese characters. From 1891 until 1949 their production was marked "made in China." but, because of domestic instability in China (the Boxer Rebellion, the Republican Revolution, regional Warlords, Civil War, Japanese aggression, etc.), there was relatively little trade with that country during that period. From 1949 to the mid 1970s there were no trade relations with mainland China. The island of Taiwan, however, became a major source for gee-gaws during the 1960s until it also moved on to pricier electronic items. Taiwanese production from this era is marked "made in Republic of China" or "made in China (R.O.C.)" to distinguish from "Red" China. In the mid 70s, trade gradually resumed with the mainland and their production is marked "Made in the People's Republic of China." In 1978, the United States fully normalized relations with mainland China and their production again became "made in China" while R.O.C. production came to be labeled "made in Taiwan."
