AP Explains: What's behind latest India-China border tension

Indian officials say the latest row began in early May, when Chinese soldiers entered the Indian-controlled territory of Ladakh at three different points, erecting tents and guard posts. China has sought to downplay the confrontation while providing little information. China has objected to India building a road through the valley connecting the region to an airstrip, possibly sparking its move to assert control over territory along the border that is not clearly defined in places.
