On 27 August 2025 the Royal Government of Cambodia issued Sub-Decree No. 161, amending Annex II (List of Categorization of Investment Activities) of Sub-Decree No. 139 of 26 June 2023 — the principal implementing decree of the 2021 Law on Investment (Royal Kram NS/RKM/1021/014). The amendment reclassifies investment activities in the production of electricity generated from renewable energy from Group 2 (medium-technology investment activities) to Group 1 (priority-sector investment activities), the highest-tier category under Cambodia's CDC-administered Qualified Investment Project (QIP) route. Group 1 elevation entitles qualifying RE-generation projects to a nine-year corporate income tax holiday (the maximum under the Annex IV incentive matrix), full customs-duty exemption on imports of construction materials, production equipment, and production inputs, priority-sector premiums, accelerated CDC investment-licence processing, and Special Economic Zone overlays where applicable. The reclassification reflects Cambodia's Cambodia Power Development Master Plan 2022-2040, which targets 70% renewable energy in the national power mix by 2030. Sub-Decree 161 is the foundational KH-issuer post-2021 Investment Law implementing decree for the RE sector, providing the regulatory anchor for project bankability assessments under Cambodia's evolving competitive-auction (post-feed-in-tariff) pricing regime being structured by the Ministry of Mines and Energy and the Electricity Authority of Cambodia (EAC). It brings Cambodia into alignment with parallel ASEAN investment-incentive-amendment instruments in Vietnam, Laos, and Thailand.

On 22 June 2025, Cambodian Prime Minister Hun Manet ordered an immediate and complete halt of all fuel and gas imports from Thailand, effective from midnight that night (00:00, 23 June 2025). The order came amid a rapidly escalating Cambodia-Thailand border dispute following the killing of a Cambodian soldier in a disputed border area the previous month, and followed Cambodia's closure of two land border checkpoints with Thailand the same day. Thailand exported an estimated 2.3 billion litres of fuel to Cambodia in 2024 — about 20% of Thailand's total fuel exports, worth roughly THB 48 billion (USD 1.5 billion) — making Cambodia one of the largest overseas markets for Thai state energy company PTT. Hun Manet stated Cambodian fuel importers have adequate capacity to source supply from alternative countries, and separately ordered strict legal penalties, including licence revocation, against any company found smuggling Thai-origin fuel into Cambodia.

On 13 June 2025 the Ministry of Environment (MoE) and the Ministry of Mines and Energy (MME) jointly issued Interministerial Prakas No. 4838, amending Cambodia's environmental-impact-assessment classification rules for all construction and mining business projects. The Prakas mandates that all businesses conducting construction and mining projects — including artisanal enterprises (investment <USD 50,000) and small-scale enterprises (USD 50,000–250,000) previously outside the formal EIA architecture — must sign an environmental-protection letter and file it with the MME prior to commencing operations; no project may operate in areas designated off-limits by the MME. The first joint MoE+MME prakas on environmental compliance extends Cambodia's EIA architecture to the full spectrum of mining-sector operators, building on the Environmental and Natural Resources Code (June 2023) and Prakas No. 8 (February 2024, EIA consulting-firm accreditation standards), and cross-references Prakas No. 3591 (May 2025) for the investment-size classification thresholds.
