Chad withdrew the licenses of China National Petroleum Corporation’s local unit after saying the company failed to pay a $1.2billion fine for environmental violations.
The government and oil exploration company failed to agree on the payment and the licenses were annulled, Ministry of Energy spokesman Bertin Djim said.
“The Chinese say the fine is too high, they’ve proposed to pay on condition of leveraging it against oil output, which was refused by the authorities,” Djim said.
A presidential decree dated July 29 and published late on Thursday said all five licenses of the CNPC unit had been revoked.
The government of the central African nation imposed the fine in March and two months later banned all exploration by the company.
CNPC was guilty of “harmful practices” including “land-filling polluted sites” without treating them beforehand, according to Energy Minister Djerassem Le Bemadjiel.
Crude spills in southern Chad prompted the government to halt drilling by CNPC from August to October last year.
CNPC has been operating in Chad since 2003 and owns 60% of an oil refinery in the capital, N’Djamena.
