evidence: Laotian troops have been encroaching on Cambodian territory in the border province of Preah Vihear for more than a week, with Laos claiming the territory as its own, military officials said on Friday. [...] Laotian soldiers entered and occupied Cambodian land near the Tonle Rapov river in the Mom Bei, or three angles, area of Chheb district since August 14, Cambodian Army spokesman Mao Phalla said. [...] In September 2018, Prime Minister Hun Sen and his Laotian counterpart Thongloun Sisoulith agreed to designate O’Tangav, a disputed area in Stung Treng province’s Siem Pang district, as a "no man’s land" and increase joint troop patrols following a 2017 standoff, the Phnom Penh Post reported.
