While governor, Aspinall dealt with a number of issues, including educational system reform and the subsequent resignation of many teachers and school personnel. He signed a bill from the American Samoa Fono that would eventually give American Samoa a Delegate to the United States House of Representatives in the 1980s. He made a number of controversial decisions, including forbidding Korean and Samoan intermarriage. He helped bring an end to extreme violence between Korean and Chinese fisherman in Samoan waters.
Along with traditionally garbed island chiefs, Aspinall was one of the first officials to greet and congratulate the crew of Apollo 10 after the success of their mission.[5]
He drew criticism for forbidding a Samoan woman from marrying a Korean man; the two sued the governor. Aspinall defended his decision by stating he was keeping disgruntled fishermen from jumping ship in Samoa; he sought to keep Samoa "for Samoans", despite the fact that he married a Samoan woman himself.[3]
Aspinall had to contend with violent clashes between Korean and Chinese ethnic groups who fought with knives and clubs off the shore. He requested riot gear to put down the violence. The incidents began when a Korean fishing boat rammed a Chinese one, ultimately causing it to sink in the storm. The governor had to separate Japanese, Chinese, and Korean vessels to keep the fishing companies running between the islands.[6] At one point, Aspinall had to close the port of Pago Pago.[7]
