Accordingly, the corporation will invest about VND500 billion (US$22.4 million) into a project to bury telecom cables underground in the city. 

Other partners who joined the MoU include Viettel Group, Vietnam Post and Telecommunications Group (VNPT) and Hanoi Electricity Corporation (EVN Hanoi), with a total investment estimated at VND3 trillion. 

Speaking at the event, Le Nam Tra, chairman of MobiFone's member council, said the corporation was honoured to contribute to the project.

"This is a big and meaningful project for the city's socio-economic development, which contributes to build a more modern and civilised capital city," Tra said.
