Retail investors in the Bank of China's oil bao, or "treasure", a speculative vehicle linked to crude futures, took a hit as the May contract for West Texas Intermediate settled at an astonishing -$37.63 a barrel on April 20th.

In general, though, plunging prices have served Chinese buyers rather well.
