Seeing "Made in China" on fine bone china indicates the country of manufacture—but it doesn't guarantee the product meets the traditional European definition of fine bone china.
Fine bone china originated in 18th-century England (Josiah Spode). Its defining characteristic: ≥30% bone ash (typically ~50%), derived from calcined cattle bones. This gives the porcelain exceptional whiteness, translucency, strength, and a resonant "ring."
China is now the world's largest ceramics producer. Many factories produce high-quality bone china that meets or exceeds the traditional standard. However, some items labeled "fine bone china" from China may contain lower bone ash percentages or substitute other fluxes, resulting in a product that is technically porcelain or "new bone china" (which uses synthetic alternatives).
In short, "Made in China" denotes origin, not necessarily composition. Discerning buyers should verify the brand's standards and product specifications.
