Palestinian Interpol membership was approved during a secretive meeting of Interpol representatives at it's annual general assembly in China on September 26, 2017. Membership for Palestine as well as the Solomon Islands was approved in a vote of 75 in favor, 24 against, and 34 abstentions. With the additions of Palestine and the Solomon Islands, Interpol has 192 members. The International Police Organization, more commonly referred to as Interpol, was established in 1923 and facilitates the sharing of intelligence and information to solve crimes that cross international borders.
Israel strongly opposed Palestinian membership in Interpol, and had for years been involved in campaigns against the entity's membership. Israel successfully blocked Palestinian efforts to join Interpol at the organization's 2016 annual meeting in Indonesia.
