10 Mid-Sized Contract Manufacturers with Operations in China and Southeast Asia

As companies reevaluate their supply chains to reduce overreliance on China, the China +1 strategy has become a key focus. This approach includes keeping some production in China while expanding to other countries like Vietnam, Thailand, or Mexico, which all offer more flexibility and reduce the risk of overrelying on a single country.

But not every manufacturer is equipped to support this shift. Many large contract manufacturers prioritize high-volume clients, leaving smaller or mid-sized brands underserved. That’s where mid-sized contract manufacturers (with 200 to 5,000 employees) come in. While the largest contract manufacturers typically focus on servicing larger brands, that doesn’t mean smaller or medium-sized companies are limited to working with single-location suppliers. There are plenty of capable, mid-sized contract manufacturers that offer operations in China and Southeast Asia, making the China +1 strategy accessible to a wider range of companies.

In this blog, I’ll list out 10 contract manufacturers that fit this profile. Each has production capabilities in China along with operations in Southeast Asia, making them well-positioned partners for companies pursuing a China +1 strategy.

Why Choose a Contract Manufacturer with Multi-Country Operations?

Working with a supplier that operates in both China and another country can offer significant strategic advantages. Rather than relying on a single country for production, these manufacturers give you options, flexibility, and resilience when supply chains face disruptions.

One major advantage is the ability to shift production in response to changing tariff policies or rising costs. For example, some companies keep tooling in China but move final assembly to Southeast Asia to take advantage of lower tariffs and labor costs. Others use dual-country production to balance lead times, labor capacity, or raw material availability.

Partnering with a multi-country contract manufacturer also simplifies supply chain diversification. Instead of onboarding separate suppliers in different countries, you get the benefit of working with one partner that can manage operations across multiple geographies.

For companies exploring a China +1 strategy, mid-sized contract manufacturers with facilities in more than one country make the transition smoother. They offer more flexibility than large multinationals that may require massive order volumes, while still providing the geographic footprint needed to de-risk your supply chain.
