In 1882, the United States and Korea established the United States-Korea Treaty of 1882, which ended Korea's self-imposed isolation. The establishment of diplomatic relations between the United States and Korea paved the way for Korean immigration to Hawaii in the late 1880s. In the early 1900s, Korean immigrants began making their way to Los Angeles, where they created communities based around ethnic churches. As the number of Koreans increased to the hundreds, their residential and commercial activities spread to the southwestern corner of the Los Angeles business district, putting them within walking distance of Little Tokyo and Chinatown.
