From the comments:
Maize was introduce to China in the middle of the 16th Century and spread pretty rapidly through the region. It appears to have been a major driver of the rapid population increase in the 1700s.

A certain Chinese herbal book presented to the emperor in 1505 shows a drawing of maize under the caption of Yiyi-ren (Job's Tears). Also, a Chinese poem written around 1368 contains a term yumi, which indicates maize. These new findings offer clear evidence that maize existed in China in the pre-Columbian era, or before 1492.
