What is the One China Policy and why does it matter

In Tashkent on October 17, Uzbek President Shavkat Mirziyoyev sat down with Chinese Premier Li Qiang and did something that might seem routine to a diplomat but is anything but for a global economy. He reaffirmed his country’s support for the One China policy. This is not just a polite nod. It is a specific diplomatic commitment that acts as a gatekeeper for economic engagement with Beijing. When you ask what the One China policy is, the answer is rooted in sovereignty. It is the principle that Taiwan is an inseparable part of China’s territory. Any nation that wants to maintain smooth trade, investment, or strategic dialogue with China must recognize this stance.

For those following the US-China trade tensions, this concept is the invisible foundation under the table. It explains why certain countries get access to massive infrastructure projects while others face diplomatic friction. The policy is not a single law but a consistent position held by the Chinese government. It dictates that Taiwan operates under its own local administration but does not have sovereign status in the eyes of Beijing. This framework influences who gets to sit at the negotiating table for the trillions of dollars in trade that flow across the Pacific and into Central Asia.

The Diplomatic Gatekeeper

The core of the One China policy is a rejection of formal recognition for Taiwanese independence. China claims sovereignty over the island and opposes any official diplomatic relations between other states and Taipei. This is not a new idea, but it is a hard line in modern geopolitics. For a country like Uzbekistan, which has a history of balancing relationships with major powers, this commitment is a specific choice. In a 2024 joint statement, Uzbekistan confirmed it would not establish official diplomatic relations or conduct official exchanges with Taiwan. This is the practical application of the policy in a bilateral context.

You see this same pattern repeating in other regions. In Montenegro, President Jakov Milatovic met with Chinese Foreign Minister Wang Yi in Cetinje on October 18. Milatovic explicitly stated that Montenegro firmly adheres to the one-China principle. This was not a passing comment. It was a central part of the diplomatic exchange. Wang Yi, in turn, expressed China’s appreciation for this firm adherence. The message is clear. Beijing values and rewards those who align with its territorial stance. This alignment is often cited as the political foundation for deepening bilateral relations, especially when those relations involve significant economic stakes.

Economic Incentives and Strategic Alliances

Why do leaders make this commitment? The answer is often tied to the sheer scale of Chinese investment. In the talks in Tashkent, officials highlighted a portfolio of joint projects worth nearly $60 billion. There are more than 6,000 joint ventures involving Chinese companies in Uzbekistan. These are not small deals. They span renewable energy, nuclear power, mineral extraction, and metallurgy. The One China policy is the diplomatic currency that helps unlock this level of economic cooperation. It signals to Beijing that a partner is stable and aligned on core issues, which reduces the political risk for Chinese investors.

The China-Kyrgyzstan-Uzbekistan railway is a prime example of this dynamic. The project is expected to stretch approximately 532 kilometres and cost around $4.7 billion to build. It is a strategic transport link that will improve connectivity between China and Central Asia. By the end of September 2026, construction had already begun on 27 of the 29 planned tunnels. This level of infrastructure development is a direct result of the political trust that the One China policy helps to cement. It is a tangible benefit for a country that is looking to modernize its transport networks and boost its trade flows with its eastern neighbor.

A Consistent Global Stance

The policy is not limited to Central Asia or the Balkans. It is a universal requirement for any nation seeking a robust partnership with China. In the case of Montenegro, the 20th anniversary of diplomatic relations is being used as a moment to review and elevate ties. Wang Yi noted that China and Montenegro share a history of anti-fascism and a spirit of resilience. He mentioned the restoration of the Tara River Bridge, a project that symbolizes the deepening connection between the two nations. This cultural and diplomatic goodwill is underpinned by the shared understanding of the One China principle. It creates a stable environment where economic and trade cooperation can flourish without the constant threat of diplomatic breakdown over territorial issues.

For the United States, this creates a complex web of alliances. While Washington often pushes for a rules-based international order, many of its partner countries are finding ways to engage with Beijing on their own terms. The One China policy is a key part of that engagement. It is a non-negotiable element for China, and for many countries, it is a manageable cost to pay for access to Chinese capital, technology, and infrastructure. This dynamic is reshaping the global economic landscape, creating new corridors of trade and influence that bypass traditional Western-dominated frameworks.

The Future of Diplomatic Alignment

As we look toward 2026 and beyond, the One China policy remains a critical factor in international relations. It is not just a historical artifact but a living, breathing part of modern diplomacy. For countries like Uzbekistan and Montenegro, it is a tool to secure investment and strengthen their position in the global economy. For China, it is a way to protect its core interests and build a network of reliable partners. The policy is simple in its definition but complex in its implications. It dictates who gets to play on the global stage and on whose terms.

The next step for these nations is to continue to deepen these economic ties. Uzbekistan and China are discussing raising bilateral trade to $30 billion in the coming years. This is a massive goal that requires a stable political foundation. The One China policy provides that foundation. It is the silent partner in these economic deals, the invisible hand that guides the flow of capital and trade. Understanding this policy is essential for anyone trying to make sense of the current state of US-China relations and the broader global economic order.
