Am I going to run into issues?
No tissues if you run into to issues. Neil you will be going the other direction, enetering into China so maybe not a problem. However the Chinese embassy website might have information on non allowable items for you. I know it is short notice since you will be leaving soon. Oh the headaches of rush planning.
Restricted items
Please put the following items in your checked baggage.
*. Knives (including hunting knives, swords, and pocket knives)
*. Scissors and any other sharp/bladed objects, such as ice-picks, and nail clippers

From China air website - so as David said - looks okay for you.
