Cambodia's Manufacturing Boom Raises New Questions About Supply Chain Independence

Cambodia has emerged as one of Southeast Asia's fastest-growing manufacturing destinations, benefiting from the global push toward China-plus-one sourcing strategies. Rising labor costs in China, geopolitical tensions, and ongoing trade uncertainty have encouraged multinational companies to explore alternative production locations, helping Cambodia attract significant foreign investment and expand its industrial base.

The country's manufacturing sector has experienced substantial growth in recent years. According to Cambodia Investment Review, the country attracted approximately US$5.2 billion in foreign direct investment (FDI) in 2025, representing a 20% increase from the previous year. Manufacturing investment alone reportedly grew by nearly 50%, driven by industries such as garments, footwear, travel goods, electronics, and light manufacturing.

On the surface, these figures appear to reinforce Cambodia's position as an emerging alternative to China.

However, a closer examination of the investment landscape reveals a more nuanced reality.

While Cambodia is often promoted as a diversification destination, Chinese investors accounted for more than 70% of total FDI inflows in 2025, according to both Cambodia Investment Review and The Phnom Penh Post. This raises an important question for global manufacturers seeking to reduce their exposure to Chinese supply chains: how diversified is production if much of the capital behind it still originates from China?

The answer extends beyond ownership.

Many manufacturing operations in Cambodia continue to rely heavily on Chinese machinery, production equipment, technical expertise, supplier networks, and intermediate components. Data from Cambodia's Ministry of Industry shows that Chinese investors are involved in more than half of the country's industrial factories, representing billions of dollars in cumulative investment.

As a result, some facilities operating within Cambodia remain deeply integrated into broader Chinese industrial ecosystems.

This distinction is becoming increasingly important as governments in the United States and Europe tighten scrutiny on supply chain transparency, transshipment practices, and rules-of-origin compliance. Regulators are paying closer attention not only to where products are assembled, but also to where components, raw materials, and investment originate.

For procurement and sourcing leaders, diversification is no longer measured solely by geography.

A factory located outside China may provide some degree of geographic separation, but companies are increasingly being asked to evaluate supplier concentration, ownership structures, and upstream sourcing dependencies when assessing supply chain resilience.

Recent investments further highlight the strength of Cambodia's ties to Chinese industry. Chinese manufacturers continue to expand operations in the country, including major projects such as BYD's vehicle assembly facility in the Sihanoukville Special Economic Zone. These investments contribute to Cambodia's industrial development while simultaneously reinforcing the close economic relationship between the two countries.

This does not diminish Cambodia's growing importance within global manufacturing networks. The country continues to attract investment, expand industrial capacity, and strengthen its role in regional supply chains.

What it does suggest is that the next phase of supply chain strategy requires a deeper level of analysis than simply selecting a factory location.

As multinational companies reassess risk exposure in an increasingly fragmented trade environment, understanding who owns, finances, and supplies a manufacturing operation may become just as important as understanding where it is located.

Cambodia's manufacturing sector continues to grow, but its evolution also highlights a broader reality facing global supply chains: diversification is no longer just about moving production. It is about understanding the entire ecosystem behind it.
