It is the latest sign of falling Chinese financial support for infrastructure projects across Africa, after years of major Chinese lending for railway, energy and other projects.
A spokesman for state oil company NNPC, which is building the 614-km (384-mile) Ajaokuta-Kaduna-Kano (AKK) pipeline, said it was still negotiating with the Chinese lenders – Bank of China and Sinosure – to cover $1.8 billion of the project cost.
“There’s no cause for alarm,” the spokesman said, without saying whether NNPC was turning to other lenders.
Bank of China said it would not comment on specific deals. Sinosure did not respond to a request for comment.
The Nigerian ministries of transport, finance and petroleum also did not reply to requests for comment.
Chinese bank lending to African infrastructure projects has fallen across the continent, from $11 billion in 2017 to $3.3 billion in 2020, a Baker McKenzie report said in April.
With the continent facing an estimated annual $100 billion infrastructure investment deficit, the loss of Chinese funding leaves a big gap to fill.
Nigeria began building the AKK pipeline in June 2020, saying it would help generate 3.6 gigawatts of power and support gas-based industries along the route. The project was to be funded under a debt-equity financing model, backed by sovereign guarantee and repaid through the pipeline transmission tariff.
NNPC awarded engineering and construction work along three sections of the pipeline to Oando, OilServe, China First Highway Engineering Company, Brentex Petroleum Services and China Petroleum Pipeline Bureau.
Transportation Minister Rotimi Amaechi said this month Nigeria was negotiating a mix of loans from Chinese and European lenders to fund railway projects, after media reports said it had initially planned to rely primarily on Chinese banks.
