KAZINFORM Samsung Group, South Korea's biggest family-controlled conglomerate, said Wednesday that it will invest 180 trillion won (160 billion US dollars) and hire 40,000 more employees for the next three years.

The investments, which will be primarily led by Samsung Electronics, will be used for the company to add artificial intelligence researchers, to be a global player in next generation telecoms technology and to boost its presence in electronics components for future cars.

Jay Lee, the vice chairman of Samsung Electronics, is appealing that conviction after being released from jail in February with a suspended sentence.

Samsung plans to allocate 25 trillion won in such fields. The company also will expand C-Lab, its internal venture incubation program, and work with the Korean government to establish and run software education centers across the country.
Samsung Electronics shares were little changed.
