Sun Group, one of Vietnam’s largest real estate developers, plans to invest more than VND7.35 trillion dong ($283 million) in a large-scale eco-tourism and cable car complex in the northern province of Lang Son, which borders China.

At a meeting with Lang Son officials on Tuesday, representatives of Sun Group discussed final preparations for the Mau Son eco-tourism and cable car project, which has been in planning for several years and is now moving toward construction.

The project was first approved in May 2018 and later revised in April 2022, when Lang Son formally approved Sun Group as the investor. The development covers more than 692 hectares and is divided into three main zones.

According to Sun Group, the overall master plan comprises three sub-areas - Xuan Man, Phat Chi and Ma Son - and includes a cable car system, spiritual and cultural facilities, entertainment zones, resorts, and commercial and service complexes.

The project will be implemented in two phases. Initial construction will focus on the cable car system and core tourism and leisure facilities. Phase one, which includes the cable car line and a spiritual complex at the Mau Son summit, is scheduled to begin shortly after the Lunar New Year (Tet) holiday in February 2026, the company said.

Sun Group pledged to accelerate construction and adhere to the approved schedule.

Provincial leaders said the project would play a strategic role in developing Mau Son into a national tourism destination and committed to supporting the developer to ensure timely execution.

Mau Son is a mountainous area located about 30 km from Lang Son town, near the Vietnam-China border. At elevations of 1,000 to 1,500 meters above sea level, it is known for its cool climate, primary forests, and waterfalls, and is among the few locations in Vietnam that sometime experience frost and snowfall in winter.
