English is effectively half-French, like French was half-Latin, which in turn was half-Greek. Europeans basically moved from a language to its immediate cousin, for more than 2000 years.

Han might be half-something too but it's definitely not something anybody ever spoke in Europe, South-America, or Africa. Europeans will likely never speak Chinese in numbers comparable to modern-day English.

French and English have much much more in common than English and Mandarin though.
