The Flynn Effect in China??

Data are reported for intelligence of children in China assessed by the Combined Raven’s Test in 1988, 1996 and 2006. The IQ of the samples increased by 15.0 IQ points over 18-year period. The British IQ of China in 1988 and 2006 is estimated as 94.8 and 109.8, respectively.

That is from a new paper by Mingrui Wang and Richard Lynn.  Via a loyal MR reader.  Speculative!
