The Khujand International Airport in Tajikistan is set to receive a $3.9m loan from the European Bank for Reconstruction and Development (EBRD) to modernise its runway and control equipment.
Earlier in 2013, the bank agreed to provide a $3m loan to the airport.
The airport is being modernised in a bid to increase air traffic safety, especially under challenging weather conditions.
Khujand International Airport is set to receive an emergency upgrade of the runway.
It also plans to acquire and install new high-intensity lights, distance-measuring equipment and radio navigation equipment.
EBRD Russia and Central Asia infrastructure director Ekaterina Miroshnik said: "Khujand is an ancient city which used to be at the heart of global trade.
"For centuries, Khujand was a major staging point on the northern Silk Road."
The EBRD has invested about $610m in the country since it commenced its operations in Tajikistan.
In June this year, the bank provided a 15-year, €42.5m loan to support JSC Astana International Airport.
The expansion was aimed at catering to the increasing flow of traffic and spikes that are expected during future events such as Astana Expo in 2017.
Turkey's Dalaman Airport also received €175m loan from the bank in February for the construction and operation of a new domestic terminal.
