Pakistan and Palestinian Authority have a very close and political relationship. During the 1948 Palestine War (1947–1949), Israel's diplomatic mission in Washington received information that Pakistan was trying to provide military assistance to the Arabs, including rumors that a Pakistani battalion would be sent to Palestine to fight alongside them. Pakistan bought 250,000 rifles in Czechoslovakia that apparently were meant for the Arabs. Also, it became known that Pakistan bought three planes in Italy for the Egyptians. The Pakistan Air-Force participated in the 1967 and 1973 Arab–Israeli wars, Pakistani pilots flying Jordanian and Syrian planes downed some Israeli planes, whereas in the 1982 battle for Beirut between Israel and the PLO, fifty Pakistani volunteers serving in the PLO were taken prisoner by Israel. After the 1973 war, Pakistan and the PLO signed an agreement for training PLO officers in Pakistani military institutions. Pakistan and the Palestine Liberation Organization (PLO) had developed close ties. The PLO was first recognized as the sole legitimate representative of the Palestinians at an Islamic summit in Lahore in February 1974. This was approved six months later at an Arab summit in Rabat. PLO missions in Karachi and Islamabad (Pakistan's capital since 1960) received full diplomatic recognition in 1975. Also in 1975, Pakistan had supported and voted in favor of UN General Assembly Resolution 3379 which had equated Zionism with racism (the resolution was later revoked with Resolution 4686 but Pakistan voted against revoking it). During the First Intifada that began in 1987, pro-PLO rallies were held in Pakistan and the government sent the organization food and medical supplies. After the Palestinian Declaration of Independence on November 15, 1988, Pakistan then recognized the Palestinian Authority on 16 November 1988 and had established full diplomatic relations with it by the end of 1989.
