With assistance from Libya (which asserted a claim to the northern Chadian territory called the Aouzou Strip), Goukouni regained control of the capital and other urban centers and Habre retreated into Sudan.
In 1994 the International Court of Justice confirmed Chadian sovereignty over the Aouzou Strip, effectively ending residual Libyan occupation of parts of Chad.
This leads to the conclusion that Paris sees this round of armed confrontation in Chad as part of an internal conflict that neither invokes the activation of the 1976 military cooperation agreement nor requires the use of the French elite forces deployed in Chad since the war with Libya over the Aouzou Strip
in the 1980s.
Libya's tensions with Chad over the Aouzou Strip
appear to have been shelved, at least for the time being.
Goukouni and Habre themselves split, largely over a disagreement about concessions to Libya in the Aouzou Strip. Habre then agreed to join Malloum's government (Conseil Superieur Militaire-CSM) as prime minister in 1978, Malloum thereby retaining the presidency.
The important exception was the Aouzou strip and the contiguous region of Tibesti.
Conflict over the Aouzou Strip was at its most intense between 1986 and 1987 (the "Toyota War", so-called on account of the rapid and stunning mobile success of Habre's light armored all-terrain vehicles).
THERE continue to be political problems both at home and abroad, although a very welcome development has been the agreement signed by Libya and Chad to end their 10-year conflict over the status of the supposedly mineral-rich Aouzou strip
. The anticipated upturn in the hydrocarbons sector has materialized, however, and Libya is reported to be receiving perhaps its highest oil revenues since those enjoyed during the oil boom of the 1970s.
However, it is notable that Chad's ten years of hostility with Libya came to an end in mid-1989 when a peace agreement was signed, as a result of which Libya's claim to the Aouzou strip
in the Tibesti mountains of northernmost Chad has been abandoned.
