formed a foundation called "Aznavour for Armenia" and composed the song as a call for help for the Armenians. It took six weeks from the creation of the song to completion of the disc and with almost two million copies sold, the foundation was able to build 47 schools and three orphanages for the victims of the disaster. Rock Aid Armenia, also known in earlier stages as Live Aid Armenia, was a humanitarian effort by the British music industry to raise money to help those affected by the earthquake. A monument, Armenian Earthquake, expressing the appreciation of the Armenian people for assistance from the U.S. was erected in Washington, D.C. in 1990. Response Gorbachev set aside 5 billion rubles (about US$8 billion) in funds for a start on what would likely be a recovery cost that would exceed the cleanup bill for the 1986 nuclear and radiation accident in Ukraine. While foreign doctors did assist with the Chernobyl incident, the Soviet relief effort after the earthquake was augmented by the largest foreign cooperation since World War II. That deluge of western aid was a byproduct of the disaster that may have had a positive effect on Soviet Union–United States relations. The cost of rebuilding would be a severe obstacle for Perestroika, Gorbachev's plan for economic restructuring. Another adverse effect of the disaster was that the Armenians were already distrustful of Gorbachev's dismissal of their claims to the disputed territory of Nagorno-Karabakh, which the Armenians had been contesting with neighboring Azerbaijan. The tensions between the two countries prior to when the earthquake struck heightened amid reports of festivities being held and celebratory messages arriving from Azerbaijan. The world responded rapidly to the disaster in Leninakan and Spitak, with much of Europe sending cargo aircraft loaded with medical supplies, rescue equipment, and trained personnel to assist in the recovery, and even more reinforcement coming in from Latin America and the Far East. Mikhail Gorbachev was in New York on his first day of visits with Ronald Reagan and George H. W. Bush at the time of the earthquake, and once the scale of the disaster was realized, a quick departure was made back to Armenia, with the Kremlin formally asking for American help. Washington immediately responded with offers of doctors, medical equipment, and rescue teams, and by the first weekend the first US plane arrived in Yerevan with search and rescue teams
