Uzbekistan and Kazakhstan, Central Asia’s two biggest nations, started the construction of the International Centre for Trade and Economic Cooperation, on the border between the two countries, Uzbekistan’s government said.

The centre’s capacity is estimated to be 35,000 people and 5,000 trucks a day, in both directions.

“Unique in Central Asia, the project will not only be mutually beneficial but will also give additional impetus to the development of trade and economic relations in the whole region,” Uzbekistan’s government said in a statement.

Kazakhstan is Uzbekistan’s third largest trading partner after China and Russia.

The two countries discussed the strengthening of bilateral relations during the foreign minister of Uzbekistan’s official working visit to Kazakhstan in February.
