Cambodia and Thailand escalated their troop buildup Thursday at disputed territory near a historic border temple despite their agreement to hold talks next week to defuse the tensions, a Cambodian general said. Cambodian Brig Gen. Chea Keo said the Thais now have more than 400 troops near the Preah Vihear temple, up from about 200 the day before, and Cambodia has about 800 troops there, up from 380 the day before. The border around Preah Vihear has never been fully demarcated, the Associated Press reported.
