[168] Three years later, after China had agreed to treaty revisions, Congress tried again to exclude working class Chinese laborers; Senator John F. Miller of California introduced another Chinese Exclusion Act that blocked entry of Chinese laborers for a twenty-year period.[169] The bill passed the Senate and House by overwhelming margins, but this as well was vetoed by Arthur, who concluded the 20-year ban to be a breach of the renegotiated treaty of 1880. That treaty allowed only a "reasonable" suspension of immigration. Eastern newspapers praised the veto, while it was condemned in the Western states. Congress was unable to override the veto, but passed a new bill reducing the immigration ban to ten years. Although he still objected to this denial of entry to Chinese laborers, Arthur acceded to the compromise measure, signing the Chinese Exclusion Act into law on May 6, 1882.[169][170] The Chinese Exclusion Act attempted to stop all Chinese immigration into the United States for ten years, with exceptions for diplomats, teachers, students, merchants, and travelers. It was widely evaded.
