[MRCA] eLORAN question

Remember that the map is created by REPORTS of trouble.  
I'd think there is little or no reporting of GPS problems from the areas you mention (China and North Korea, and to a lesser degree Russia) because they do not share that sort of information.

 The map shows interference problems over the Middle East, Western Europe, and North America ( mostly the USA ).  Interesting that there are no problems over China, most of Russia, and North Korea.

GPS/GNSS outages are a real problem.  My research seems to point to four main issues:
- GPS jamming.- GPS spoofing.- Environmental noise interference.- Unintentional interference from other radio services.
Air safety is driving concern but of course it is an issue for all GPS users.

Here's a map showing GPS loss incidents for Aug 2021- Dec 2022:
