Foreign policy
Relations between Zaire and Belgium wavered between close ties and open hostility during the Mobutu years. More often than not, Belgian decision-makers responded indifferently when Mobutu acted against the interests of Belgium, partly explained by the highly divided Belgian political class. Relations soured early in Mobutu's rule over disputes involving the substantial Belgian commercial and industrial holdings in the country, but they warmed soon afterwards. Mobutu and his family were received as personal guests of the Belgian monarch in 1968, and a convention for scientific and technical cooperation was signed that same year. During King Baudouin's highly successful visit to Kinshasa in 1970, a treaty of friendship and cooperation between the two countries was signed. Mobutu tore up the treaty in 1974 in protest at Belgium's refusal to ban an anti-Mobutu book written by left-wing lawyer Jules Chomé. Mobutu's "Zairianisation" policy, which expropriated foreign-held businesses and transferred their ownership to Zairians, added to the strain. Mobutu maintained several personal contacts with prominent Belgians. Edmond Leburton, Belgian prime minister between 1973 and 1974, was someone greatly admired by the President. Alfred Cahen, career diplomat and chef de cabinet of minister Henri Simonet, became a personal friend of Mobutu when he was a student at the Université Libre de Bruxelles. Relations with King Baudouin were mostly cordial, until Mobutu released a bold statement about the Belgian royal family. Prime Minister Wilfried Martens recalled in his memoirs that the palace gates closed completely after Mobutu published a handwritten letter of the King. Because of that, Mobutu was one of only two heads of state who did not receive an invitation to the funeral of Baudouin, the other being Saddam Hussein of Iraq. Next to friendly ties with Belgians residing in Belgium, Mobutu had a number of Belgian advisors at his disposal. Some of them, such as Hugues Leclercq and Colonel Willy Mallants, were interviewed in Thierry Michel's documentary Mobutu, King of Zaire.
As then the second most populous French-speaking country in the world (it has subsequently come to have a larger population than France) and the most populous one in sub-Saharan Africa, Zaire was of great strategic interest to France. During the First Republic era, France tended to side with the conservative and federalist forces, as opposed to unitarists such as Lumumba. Shortly after the Katangan secession was successfully crushed, Zaire (then called the Republic of the Congo) signed a treaty of technical and cultural cooperation with France. During the presidency of Charles de Gaulle, diplomatic relations between the two countries gradually grew stronger and closer due to their many shared geopolitical interests. In 1971, Finance Minister Valéry Giscard d'Estaing paid a visit to Zaire; later, after becoming France's president, he would develop a close personal relationship with President Mobutu, and under his leadership, France became one of the Mobutu regime's closest and most important foreign allies. During the Shaba invasions, France sided firmly with Mobutu: during the first Shaba invasion, France airlifted 1,500 Moroccan troops to Zaire, and the rebels were repulsed; a year later, during the second Shaba invasion, France itself (along with Belgium) would send French Foreign Legion paratroopers (2nd Foreign Parachute Regiment) to aid Mobutu.
Initially, Zaire's relationship with the People's Republic of China was no better than its relationship with the Soviet Union. Memories of Chinese aid to Mulele and other Maoist rebels in Kwilu province during the ill-fated Simba Rebellion remained fresh on Mobutu's mind. He opposed seating the PRC at the United Nations. By 1972, he began to see the Chinese in a different light, as a counterbalance to both the Soviet Union as well as his intimate ties with the United States, Israel, and South Africa. In November 1972, Mobutu extended diplomatic recognition to the Chinese (as well as East Germany and North Korea). The following year, Mobutu paid a visit to Beijing, where he met with chairman Mao Zedong and received promises of $100 million in technical aid. In 1983, then Chinese Premier Zhao Ziyang announced on a trip to Zaire that the money would not have to be repaid.
In 1974, Mobutu made a surprise visit to both China and North Korea, during the time he was originally scheduled to visit the Soviet Union. Upon returning home, both his politics and rhetoric became markedly more radical; it was around this time that Mobutu began criticizing Belgium and the United States (the latter for not doing enough, in Mobutu's opinion, to combat white minority rule in South Africa and Rhodesia), introduced the obligatory civic work program called salongo, and initiated "radicalization" (an extension of 1973's "Zairianization" policy). Mobutu even borrowed a title – the Helmsman – from Mao. Incidentally, late 1974 to early 1975 was when his personality cult reached its peak.
China and Zaire shared a common goal in central Africa, namely doing everything in their power to halt Soviet gains in the area. Accordingly, both Zaire and China covertly funnelled aid to the National Liberation Front of Angola (and later, the National Union for the Total Independence of Angola) in order to prevent their former allies, the People's Movement for the Liberation of Angola, who were supported and augmented by Cuban forces, from coming to power. The Cubans, who exercised considerable influence in Africa in support of leftist and anti-imperialist forces, were heavily sponsored by the Soviet Union during the period. In addition to inviting Holden Roberto, the leader of the National Liberation Front of Angola, and his guerrillas to Beijing for training, China provided weapons and money to the rebels. Zaire itself launched an ill-fated, pre-emptive invasion of Angola in a bid to install a pro-Kinshasa government, but was repulsed by Cuban troops. The expedition was a fiasco with far-reaching repercussions, most notably the Shaba I and Shaba II invasions, both of which China opposed. China sent military aid to Zaire during both invasions, and accused the Soviet Union and Cuba (who were alleged to have supported the Shaban rebels, although this was and remains speculation) of working to de-stabilize central Africa.
Mobutu's relationship with the Soviet Union was frosty and tense. A staunch anti-communist, he was not anxious to recognize the Soviets; the USSR had supported – though mostly in words – both Patrice Lumumba, Mobutu's democratically elected predecessor, and the Simba rebellion. However, to project a non-aligned image, he did renew ties in 1967; the first Soviet ambassador arrived and presented his credentials in 1968. Mobutu joined the United States in condemning the Soviet invasion of Czechoslovakia that year. Mobutu viewed the Soviet presence as advantageous for two reasons: it allowed him to maintain an image of non-alignment, and it provided a convenient scapegoat for problems at home. For example, in 1970, he expelled four Soviet diplomats for carrying out "subversive activities", and in 1971, twenty Soviet officials were declared persona non grata for allegedly instigating student demonstrations at Lovanium University.
Moscow was the only major world capital Mobutu never visited, although he did accept an invitation to do so in 1974. For reasons unknown, he cancelled the visit at the last minute, and toured the People's Republic of China and North Korea instead.
Relations cooled further in 1975, when the two countries found themselves on opposing sides in the Angolan Civil War. This had a dramatic effect on Zairian foreign policy for the next decade; bereft of his claim to African leadership (Mobutu was one of the few leaders who refused to recognize the Marxist government of Angola), Mobutu turned increasingly to the US and its allies, adopting pro-American stances on such issues as the Soviet invasion of Afghanistan, and Israel's position in international organizations.
For the most part, Zaire enjoyed warm relations with the United States. The United States was the third largest donor of aid to Zaire (after Belgium and France), and Mobutu befriended several US presidents, including Richard Nixon, Ronald Reagan, and George H. W. Bush. Relations did cool significantly in 1974–1975 over Mobutu's increasingly radical rhetoric (which included his scathing denunciations of American foreign policy), and plummeted to an all-time low in the summer of 1975, when Mobutu accused the CIA of plotting his overthrow and arrested eleven senior Zairian generals and several civilians, and condemned (in absentia) a former head of the Central Bank (Albert Ndele). Many viewed these charges with scepticism, with one of Mobutu's staunchest critics, Nzongola-Ntalaja, speculating that Mobutu invented the plot as an excuse to purge the military of talented officers who might otherwise pose a threat to his rule. In spite of these hindrances, the chilly relationship quickly thawed when both countries found each other supporting the same side during the Angolan Civil War.
Because of Mobutu's poor human rights record, the Carter Administration put some distance between itself and the Kinshasa government; even so, Zaire received nearly half the foreign aid Carter allocated to sub-Saharan Africa. During the first Shaba invasion, the United States played a relatively inconsequential role; its belated intervention consisted of little more than the delivery of non-lethal supplies. But during the second Shaba invasion, the US played a much more active and decisive role by providing transportation and logistical support to the French and Belgian paratroopers that were deployed to aid Mobutu against the rebels. Carter echoed Mobutu's (unsubstantiated) charges of Soviet and Cuban aid to the rebels, until it was apparent that no hard evidence existed to verify his claims. In 1980, the US House of Representatives voted to terminate military aid to Zaire, but the US Senate reinstated the funds, in response to pressure from Carter and American business interests in Zaire.
Mobutu enjoyed a very warm relationship with the Reagan Administration, through financial donations. During Reagan's presidency, Mobutu visited the White House three times, and criticism of Zaire's human rights record by the US was effectively muted. During a state visit by Mobutu in 1983, Reagan praised the Zairian strongman as "a voice of good sense and goodwill".
Mobutu also had a cordial relationship with Reagan's successor, George H. W. Bush; he was the first African head of state to visit Bush at the White House. Even so, Mobutu's relationship with the US radically changed shortly afterward with the end of the Cold War. With the end of the Soviet Union's status as a world superpower, there was no longer any reason to support Mobutu as a bulwark against communism. Accordingly, the US and other Western powers began pressuring Mobutu to democratize the regime. Regarding the change in US attitude to his regime, Mobutu bitterly remarked: "I am the latest victim of the cold war, no longer needed by the US. The lesson is that my support for American policy counts for nothing." In 1993, Mobutu was denied a visa by the US State Department after he sought to visit Washington, D.C.
Mobutu also had friends in America outside Washington. Mobutu was befriended by televangelist Pat Robertson, who promised to try to get the State Department to lift its ban on the African leader.
