The Rio Grande separates "Texas from Mexico".

Explanation:

Rio Grande is a river that separates the US state of Texas from the Chihuahua and Coahuila states of Mexico. It plays the role of a natural physiographic boundary between the United States and Mexico right from a little east of Brownsville in southern Texas up to the El Paso County that is situated in northwestern Texas. The river runs a stretch of more than 3000 kilometers and drains into the "Gulf of Mexico".
