It's a scandal that just won't go away for Starbucks in South Korea. The chairman of the coffee chain's local corporate majority owner was compelled to issue a second public apology in the wake of the company's disastrous "Tank Day" promotion launched earlier this month. Many Koreans saw the campaign's name as a reference to a deadly 1980 crackdown in which hundreds of pro-democracy protesters were killed by the country's military dictatorship. The campaign was quickly scrapped, but it hasn't quelled public furor.

The marketing blunder on South Korea’s most solemn democratic anniversary has reignited a decades-old battle over how the country confronts its authoritarian past.

Chung Yong-jin’s apology came as backlash deepened over the coffee chain’s marketing campaign mocking South Korea’s pro-democracy history.
