In a striking departure from convention, China’s Ministry of Commerce has recently released policy announcements in a file format that is incompatible with Microsoft Word, requiring users to access them via WPS Office — the home-grown office suite developed by Beijing’s Kingsoft.

The move coincides with Beijing’s decision to expand rare earth export controls amid heightened tensions with the United States.

Observers see this as part of a broader strategic push for software self-reliance—and, possibly, control over document dissemination.

WPS documents use a coding structure that Microsoft’s Word cannot natively open, meaning recipients must convert or use domestic tools to view them.

Critics argue the format choice creates a barrier to transparency and access for foreign stakeholders.

China has long encouraged adoption of domestic technology alternatives in sensitive sectors, especially amid ongoing US-China frictions.

WPS Office has already secured a dominant position within government, financial, and telecommunications spheres, with more than 100 million daily users and over 600 million monthly active users nationwide.

The format shift aligns with China’s ambition to reduce reliance on foreign proprietary technologies.

The timing—during the release of stronger export control measures on rare earths, which are critical to global supply chains in electronics and defense—amplifies the potential impact.

The ministry’s choice to lock the content behind a domestic file standard raises questions over access for foreign firms, analysts, and diplomatic actors.

While China insists its technology policy is grounded in autonomy and sovereignty, this document strategy may also deepen the technological divisions already shaping global economic and regulatory competition.
