Chinese factories are different because they tend to care about about volume. It’s not uncommon for factories to give discounts of up to 30% due to a significant increase in order volume. Factory owners outside of China may be more concerned with profit margins, but the primary concern of most (if not all) of the Chinese factories I've encountered is growing revenue. Business expansion has to be a goal for all Chinese factories. In such a saturated and competitive marketplace, growing the business is the only way to ensure long-term survival.
Factories in India are much more concerned with building and maintaining relationships. Because competition is not as fierce, Indian manufacturers generally want to spend more time with sourcing agents and clients before accepting an order. Since clients are given 30 days credit, and factories are only paid 30 days after goods have been received, there needs to be an established relationship and trust between those involved in the transaction.
Bangladesh is an interesting one as well. From a price competitiveness perspective, it comes out on top by an impressive margin. Labour costs are significantly lower than in China and India. Nevertheless, the low cost comes with corresponding risks. Instances of abuses within the system, particularly in child labour, makes Bangladesh a relatively risky production destination . Unless the retailer or their sourcing agent has the capabilities to ensure necessary oversight, the risk of sourcing from there is likely to be outside many business’ risk appetites.
As long as your risks are effectively managed, sourcing from Asia has many benefits. Evaluate your business needs and ensure that you make sourcing decisions that makes the most sense for your business.
