Reagan actually vetoed it, what i find funny is this line: " President Reagan enlisted South African foreign minister Pik Botha to call Republicans on the fence." Pik Botha was one of the hardest apartheid officials, he held out until the end and wanted war. Source below.
'''Veto by President Reagan[edit]
Reagan vetoed the compromised bill on September 26, calling it "economic warfare" and alleging that it would mostly hurt the impoverished black majority and lead to more civil strife.[10] He again offered to impose sanctions via executive order, while also working with Senate Republicans on concessions to avoid them overriding his veto. Reagan's veto was attacked harshly by anti-Apartheid leaders like Desmond Tutu who said Reagan would be "judged harshly by history".[11] In the week leading up to the subsequent vote, President Reagan enlisted South African foreign minister Pik Botha to call Republicans on the fence, though this was seen to backfire.[12]
Veto override[edit]
Reagan's veto was overridden by Congress (by the Senate 78 to 21, the House by 313 to 83) on October 2.[13] This override marked the first time in the twentieth century that a president had a foreign policy veto overridden.[2] Apartheid opponents in America and South Africa applauded the vote, while critics argued that it would be either ineffectual or lead to more violence.[12][14]'''
