The chief executive of Starbucks Korea was dismissed on Monday after the company launched a promotional campaign that deeply offended South Koreans by evoking one of the most painful chapters in the country's history — the 1980 Gwangju Uprising — on the very anniversary of its commemoration.

The campaign, called "Tank Day", offered discounts on a range of large-capacity drink tumblers. Launched on 18 May, it used the English word "tank" alongside the Korean phrase meaning "put it on the table with a sound of 'tak!'" Critics immediately pointed out that the date, 5/18, marks the beginning of the Gwangju Uprising, when military strongman Chun Doo-hwan deployed paratroopers and armoured vehicles against student-led pro-democracy protesters in Gwangju, a city roughly 270 kilometres south-west of Seoul. Over the following ten days, troops used bayonets, batons and live ammunition; victims' groups estimate that hundreds were killed, and later investigations confirmed that troops also committed rape and sexual assault. The word "tak" carried a further layer of offence: in 1987, police infamously claimed that a student activist, Park Jong-chul, had collapsed and died after an interrogator struck a desk with a "tak" sound — a lie that became a widely recognised symbol of the regime's attempts to conceal torture, and that helped spark the nationwide protests which ultimately forced Chun's government to accept direct presidential elections.

The backlash was swift. Within hours, civic groups, bereaved families of Gwangju victims and online users condemned the promotion and called for a boycott. The Gwangju-Jeonnam Memorial Coalition described the campaign as "clearly malicious mockery" and accused the company of a "biased historical consciousness". Starbucks Korea suspended the event and apologised to victims, their families and all those who had contributed to South Korea's democratisation. Starbucks' US headquarters also issued a statement acknowledging that "while unintentional, this should never have happened." President Lee Jae Myung, who had attended the official Gwangju commemoration ceremony that day, condemned the campaign on social media, writing that he was "outraged by such a low-class merchant's inhumane behaviour, which denies our country's values of basic human rights and democracy."

Shinsegae Group, the retail conglomerate whose E-Mart subsidiary holds a 67.5% controlling stake in Starbucks Korea, moved quickly to contain the crisis. Chairman Chung Yong-jin personally notified CEO Son Jung-hyun of his dismissal and ordered disciplinary measures against others involved in planning and approving the marketing event, calling it "an inexcusable mistake that trivialised the suffering and sacrifices of all those who have dedicated themselves to the democracy of this country." The controversy also drew renewed scrutiny of Chung himself, who in 2022 posted anti-communist slogans online — rhetoric long associated with South Korea's far right — and who has ties to conservative organisations abroad.

The episode carries weight beyond corporate misstep. May 18th is one of South Korea's most solemn civic dates, commemorated annually and depicted repeatedly in film and television as a moment of national trauma. Since the US parent company sold its stake in the Korean operation in 2021, Starbucks Korea has been run entirely by Shinsegae's subsidiary, meaning full responsibility for the campaign lay with local management. The incident underscores the acute sensitivity surrounding South Korea's democratic transition — and the consequences for brands that appear to trivialise it.
