Princess Urduja's gifts of rice, buffaloes, ginger, pepper, lemons, mangoes, and salt are products that are abundant in Pangasinan and India. The closely related Ibaloi people have an oral tradition of a woman named Udayan who ruled an ancient alliance of lowland and highland settlements in Pangasinan and the neighboring province of Benguet. Ibn Battuta also mentioned that Urduja had some knowledge of a Turkic language, which indicates contact with foreigners. Tawalisi was said to be in contact with Mongol-ruled Yuan China so the Turkic language may have been Mongolian.
