Starbucks Korea Sales Plummet After Tone-Deaf 'Tank Day' Campaign Sparks Outrage

Starbucks Korea has suffered a "very significant" drop in sales after a marketing campaign that evoked a brutal 1980 military crackdown on pro-democracy protesters triggered a public outcry. The chairman of Shinsegae Group, the operator of Starbucks Korea, publicly apologized and asked people not to take out anger on employees.

The controversy erupted over the "Tank Day" tumbler marketing campaign launched on the anniversary of the May 18 Gwangju Uprising, when the military government deployed troops and tanks to suppress pro-democracy demonstrations. Hundreds of people are estimated to have died or gone missing during the crackdown.

Shinsegae Group chairman Chung Yong-jin stated: "I take it very seriously that Starbucks Korea's inappropriate marketing hurt and angered many people. I will take all responsibility for the incident."

The company fired the head of Starbucks Korea and launched an internal investigation. The investigation found that the e-commerce team had been overly focused on sales amid a large volume of weekly promotional events, leading staff to approve the campaign without proper review or legal scrutiny. The incident exposed serious flaws in Starbucks Korea's risk management framework.

Starbucks Global headquarters in the US was aware of the gravity of the situation and had been receiving updates. Shares in Shinsegae initially fell but later recovered.
