Zhejiang Geely Holding Group has signed a binding deal to buy Ford Motor Co.’s Volvo Cars unit for $1.8 billion, representing a coup for the independent Chinese automaker which is aiming to expand in Europe.

The purchase gives Geely a European luxury car brand with a reputation for safety and quality at a time when China, which last year surpassed the U.S. as the world’s largest car market, is eager to improve its competitiveness by acquiring foreign automotive brands that might help it improve its technology and expand into overseas markets.
