One continent, many business cultures
"Asia" is not a strategy. The way a Japanese supplier handles a tolerance question is the opposite of the way a Vietnamese supplier handles the same question. Mistaking one for the other is one of the fastest ways to lose money.
China: speed and pragmatism
Chinese suppliers move fast, accept frequent design changes, and often reverse-engineer to a workable solution. Be very precise about specifications and quality acceptance. Build personal relationships (guanxi) — they remain the strongest predictor of long-term reliability.
Japan: precision and process
Japanese suppliers prize specifications, planning, and consensus (nemawashi). Decisions take longer, but once made they are honoured to the letter. Avoid public disagreement, never push a supplier to lose face, and expect very high adherence to delivery dates.
South Korea: speed and engineering depth
Korean suppliers combine strong engineering with fast execution. Hierarchy is steep — make sure you are talking to the right level for the question. Senior counterparts expect senior counterparts.
Vietnam and Southeast Asia: rising and varied
Vietnam, Indonesia, Thailand and Malaysia are absorbing capacity that used to sit in coastal China. Quality is improving fast but uneven. On-site audits and pre-shipment inspections matter more than averages suggest.
India: relationship-driven, flexible scope
Indian suppliers are often willing to absorb late changes and propose creative alternatives. Document agreements explicitly — verbal commitments may be remembered differently. Plan for multiple time zones if you split work across sites.
What "yes" means
Across much of Asia, "yes" can mean "I heard you", not "I commit to it". Confirm critical points by asking the supplier to repeat them in their own words and by following up in writing. Silence after a request often means "no".
Time zones, holidays and Lunar New Year
Plan Q1 deliveries with Chinese New Year (and Vietnamese Tet) in mind — factories close for two to four weeks. Indian Diwali, Japanese Golden Week and Korean Chuseok have similar effects. Build the calendar before you build the schedule.
