The Trung Khoi - Quan Ngang Factory and Office Area Project, invested by Trung Khoi Joint Stock Company, has been granted a policy by Quang Tri province since 2020. The project is built on an area of nearly 29 hectares, aiming to provide modern factories and offices for secondary investors to lease, with a total investment of more than 763 billion VND.

However, up to now, after 5 years, the project has only completed 17/21 house foundations, 9/21 workshops, 8/21 roofs and 21 transformer stations. The remaining items are unfinished, the project area has been abandoned for many years.
According to the Management Board of Quang Tri Economic Zone, the progress is slow due to the impact of the COVID-19 epidemic, the frozen real estate market and difficulties in attracting secondary investors, especially when construction planning is still facing many problems.
Currently, the project has been approved by the People's Committee of Quang Tri province to extend the progress. The investor was also restructured and renamed Nippon Solar Solar Solar Energy Joint Stock Company.

On March 28, 2025, the Provincial People's Committee issued a decision to extend the investment policy. Accordingly, by the end of the first quarter of 2025, the investor must complete the procedure for renting 3.89ha of the remaining land, applying for a construction permit and reorganizing the project. By the fourth quarter of 2027, it must be completed to attract secondary projects, filling 100% of the land.
"Currently, the project's progress has been extended. We will check and monitor closely. If there is no legitimate reason for continued delay, the project will be proposed to be revoked" - Mr. Nguyen Duc Thien, Deputy Head of the Quang Tri Provincial Economic Zone Management Board, affirmed.
