The Thai-Cambodian border has attracted close attention from regional security personnel and military analysts in ASEAN after reports surfaced that the Cambodian military received 39 T-59D main battle tanks from the People's Republic of China. Key evidence images leaked online reveal a covert nighttime operation moving large-scale military equipment.
The image series shows a convoy of low-bed trailers transporting large objects tightly covered with tarps and camouflage nets. However, the distinct shapes led experts to identify these as "tanks." Detailed location analysis found the convoy passing in front of Sihanoukville port, heading east toward Highway 4, the main route to Phnom Penh. The operation was conducted at night to conceal movements from external observation.
If Cambodia's military indeed commissions 39 T-59D tanks, what impact would this have on the ground combat power balance compared to the Royal Thai Army?
It is important to understand that the T-59D is an upgraded version of the Type 59, which China developed based on the Soviet-era T-54/55. Although the design is old, the "D" variant has undergone significant modernization.
The main armament was upgraded from the original 100mm rifled gun to a 105mm smoothbore gun (Type 83) capable of firing armor-piercing fin-stabilized discarding sabot (APFSDS) rounds and anti-tank guided missiles through the barrel.
For protection, explosive reactive armor (ERA) was added to the turret and front hull to reduce the effectiveness of high-explosive anti-tank (HEAT) warheads.
The fire control system was enhanced with thermal detection and digital ballistic computers, improving night firing capabilities.

If a confrontation occurs at the Thai-Cambodian border,
In terms of firepower and technology, Thailand’s frontline main battle tanks like the VT-4 and T-84 Oplot-M significantly outperform the T-59D. Thai tanks feature hunter-killer target acquisition systems, more accurate fire control over long ranges, and 125mm guns capable of easily penetrating T-59D armor.
Against Thailand’s M60A3 tanks, which are numerous, the T-59D represents a more evenly matched adversary due to similar 105mm gun calibers. The T-59D has the advantage of full-body ERA, while Thailand’s M60A3 benefits from stable thermal imaging and night vision systems.
