The entire site is in front of the nearby Boeng Cheung Loung lake and is surrounded by rice fields.

[11] In July 2023, Sun Chanthol of the Ministry of Public Works and Transport expressed the government's interest in connecting the airport with Phnom Penh city, possibly near the AEON mall in Mean Chey, via light rail, potentially as part of an underground metro system.

This was subscribed mostly by local Cambodian insurance companies and banks, allowing the CAIC to raise $300 million, which is then invested by the OCIC.

This followed a recent visit by Prime Minister Hun Manet to Japan,[13] which according to The Phnom Penh Post helped attract interest in investing into Cambodia.

[9] However, on March 30, 2023, the Deputy Governor of Kandal Province, Nou Peng Chandara, stated that the airport was now 44% complete during a press conference.

On 8 June 2023, local residents from four communes in Kandal province around the airport protested against the filling of land near their homes and Canal 94.

To prevent the residents from intervening, the company brought in security and fire trucks, which they used to spray water at the villagers who were armed with sticks and stones.

The village chiefs and around 100 families in Champei and Doung communes in Bati district who have been farming on the land since 1979, then asked for Hun Manet to help mediate and increase the rate to $3.

Their land is planned to be turned into a reservoir according to Chiv Kok Say, who also said that their request of a $3 rate was not feasible because their "farmlands were without title deeds".

[21] On 28 January 2024, around 80 villagers from Ampov Prey, Kadal Stueng, gathered near land allocated for the airport and called on authorities to expedite a settlement process.

[18] For the Cambodian government, the inclusion of greenery is part of the GreenSky project, which aims to make Techo a sustainable and eco-friendly airport.

GreenSky aims to do this through the use of vertical gardens, rooftop greenery, and the use of native Cambodian flora, which will improve the airport's air quality.

Alongside the use of flora, the airport management also plans to use eco-friendly practices such as the use of solar energy, rainwater harvesting, and measures to reduce waste.
