Luckin Coffee, the Chinese coffee giant, is pushing its global expansion strategy after its first foray into Singapore. Despite intense competition at home and early losses in Singapore, Luckin is eyeing the US and other markets, even as it faces a price war from its own clone competitor, Cotti Coffee. With aggressive store openings and a focus on low prices, Luckin aims to establish its presence in new markets, but the path to profitability remains uncertain.
