Truck-maker Isuzu Motors said Thursday it will enter talks with U.S. engine manufacturer Cummins Inc. on the joint development of more eco-friendly diesel engines.

Aiming to work out the details of the envisaged partnership by the end of the year, Isuzu, which terminated a capital tie-up with Toyota Motor Corp. in August, said it is also hoping to cooperate with the world's leading diesel engine-maker in the area of electrification technologies.

Isuzu's intention to form the partnership strengthened around April amid tighter environmental regulations around the world. The Tokyo-headquartered company said in a statement it will form the "most suitable partnerships in each technical area for ... business growth."

Cummins, founded in 1919, sells 1.2 million engines annually, including those manufactured for industrial purposes.
