legal - Can I say this about real countries in my fiction?

I am writing a visual novel and use a fictional country in "real-world" setting. Some cases have been bothering me and I'm not sure if it's legal to write this because it might be insulting(?):

1. 
   
   

   To place my country I had to cut a part of China, so it is located between Russia, Mongolia and China.

   
   


2. 
   

   I mention that my country's army has "some connections with Japan" and recruits children from there.

   
   


3. 
   

   I mention that my country's army shoots up Mongolian illegal immigrants at the border.

   
   

Edit: To clarify, I do not have intentions of insulting countries, just want to write what would be suitable for my story and am afraid of law suits. Also I live in Russia.

Edit: I can rephrase the question so it will sound like this: Can I assign fictional slightly negative traits to countries from real world in my fictional world?
