Here are figures on bullying from the link in the article, http://hhdw.org/wp-content/uploads/YRBS_School_IND_00001.pdf:

Asians: 16.2% in 2011, 12.3% in 2013, and 10.5% in 2015.
Pacific Islanders: 19.0% in 2011, 18.7% in 2013, and 14.7% in 2015.

These figures (from pages 2/24, 4/24, and 6/24) indicate a decline, not a "rise."
