ExxonMobil has pulled its application to secure some $2 billion of funds from the Export-Import Bank of the US (Exim) for its Rovuma liquefied natural gas mega-project in Mozambique.

The reasons behind the US giant withdrawing its 18-month old filing are unclear, although sources familiar with the US and Mozambique told Upstream that Exim’s recently revived mandate effectively forbids it lending to projects in which Chinese companies are involved.

State-owned China National Petroleum Corporation (CNPC) is a key partner in Rovuma LNG and Offshore Area 4, which will supply gas feedstock, along with Italy’s Eni, Galp of Portugal and South Korean player Kogas.
