KIEV - The Export-Import Bank of China (China Exim Bank) has opened a credit line of $372 million for Ukraine to fund the "Air Express" project, Ukraine's State Agency for Investment and National Projects said on Wednesday.

The "Air Express" project is Ukraine's biggest infrastructure project with private investments since 1991, said Vladyslav Kaskiv, the head of the State Agency for Investment and National Projects.
