Procter & Gamble initially failed to break into the Chinese diaper market with Pampers in 1998 due to cultural norms around cloth diaper usage and early potty training. To overcome obstacles, P&G conducted extensive market research to understand Chinese consumer needs and launched an advertising campaign emphasizing the sleep benefits of Pampers, backed by clinical studies. P&G also improved product quality, increased accessibility through Chinese manufacturing, and invested heavily in long-term advertising to educate the Chinese market and make Pampers the dominant brand. As a result, Pampers is now the top-selling diaper brand in China.
