LOL nice troll pic.
I personally thought that incident was rather hilarious. Did Abe intentionally chose a plane numbered 731, or was it pure coincidence and China making unnecessary connections to Unit 731 of the Imperial Japanese Army.
Either way, Abe's assistants should've known it would cause a diplomatic crisis, or maybe Abe wanted a diplomatic crisis.
On topic: China has really progress a lot in the field of frontier scientific research. After a 35 years of sending Chinese students to US to study, China has acquired a very advanced scientific community.
It probably was pure coincidence.

That's the problem, unfortunately, when certain nation(s) screen every single little thing Japan does and links these minute details as an affront to the past. Aish. Oy Vey!
I say...Le Chaim!
