Over the decades, corruption scandals have regularly rocked Samsung and other family-controlled conglomerates in South Korea that have led the country’s rapid industrialization and still dominate the export-driven economy.

In many cases, such sentences were quickly erased by presidential pardons, which have become almost an annual event, raising doubts among foreign investors hoping for tighter corporate governance in this major Asian economy.
Mr. Lee headed Samsung for more than two decades until he stepped down after the group’s former chief legal counsel, Kim Yong-chul, asserted in 2007 that Samsung had kept a stash of secret funds and run a network of bribery. The whistle-blower said Samsung used the money to influence officials, prosecutors, judges and politicians.See story here.
