Lee Kun-hee
Since 1990, Samsung has increasingly globalised its activities and electronics; in particular, its mobile phones and semiconductors have become its most important source of income. It was in this period that Samsung started to rise as an international corporation in the 1990s. Samsung's construction branch was awarded contracts to build one of the two Petronas Towers in Malaysia, Taipei 101 in Taiwan and the Burj Khalifa in United Arab Emirates. In 1993, Lee Kun-hee sold off ten of Samsung Group's subsidiaries, downsized the company, and merged other operations to concentrate on three industries: electronics, engineering and chemicals. In 1996, the Samsung Group reacquired the Sungkyunkwan University foundation.
