15,000+ contactable suppliers from the China-South Asia Expo (CSA-EXPO)
If you source from China and want to reach the markets that matter — South and Southeast Asia — there's one national-level gateway you should know: the China-South Asia Expo (CSA-EXPO), held every year in Kunming. It's where Chinese factories go specifically to meet buyers from Pakistan, India, Sri Lanka, Vietnam, Thailand and beyond. And it's where they show what they make.
We've now indexed the exhibitors from this expo into our supplier base. That's 12,050 Chinese suppliers (Yunnan is the core, but every major province shows up) plus 3,066 suppliers from South and Southeast Asia — Pakistan, Thailand, India, Sri Lanka, Vietnam, Laos, Nepal, Malaysia, Indonesia, Myanmar and more. Nearly all of them have a direct contact email. Here's what this means for buyers.
One expo, two directions of value
The CSA-EXPO is a meeting point, and our coverage reflects both sides of it:
- Chinese suppliers (12,050) — the factories exhibiting to reach South and Southeast Asian buyers. Yunnan leads with 8,085, plus Fujian, Hunan, Shandong, Chongqing, Shaanxi, Zhejiang, Hebei, Guangdong and Sichuan. The biggest cluster is green energy (about 40% are in the Green Energy pavilion), alongside green food, biomedicine and manufacturing.
- South & Southeast Asian suppliers (3,066) — Pakistan (331), Thailand (325), India (307), Sri Lanka (216), Vietnam (183), Laos (151), Nepal (139), Malaysia (130), Indonesia (128), Myanmar (112). These are regional suppliers you can reach directly.
Nearly all are contactable
Indexing means more than a name on a list. These contact details come straight from the expo's official platform — provided by exhibitors at registration — and we aligned them into our database. We also mapped the expo's business-type codes into readable categories (e-commerce, foreign trade, domestic trade, and more):
- About 100% carry a direct email — both the Chinese and regional suppliers are reachable
- Contact phones on nearly every record
- Official websites where available, so you can verify product and scale
- Company name, product category, industry, region and pavilion are aligned
So this isn't a dead exhibitor list — it's a contactable supplier pool built around the South and Southeast Asian trade route.
How to use it
Tell us the product you're sourcing and the region you want to buy from. If it fits this expo's focus — green energy, green food, biomedicine, manufacturing — we'll match you to the relevant suppliers from both the Chinese and regional pools, prioritizing those with the most complete profiles. Whether you're a buyer sourcing from China or a buyer sourcing from South/Southeast Asia, this is a direct line to vetted trade-show suppliers.
Frequently asked
How big is the supplier pool you match from?
We match from an existing base we build and continuously enrich — 1.71M+ in total, with 1.04M+ reachable via verified contact info, including 819K+ overseas reachable companies plus a China-based pool of 224K+ reachable suppliers. For buyers, what matters is the verified supplier side: Chinese trade-show exhibitors and other audited B2B sources we can match against your request and reach on your behalf. This is the existing base, not a fixed limit: if the market or category you need isn't in it yet, we collect and enrich it on demand.
