Honestly, why the secrecy? Other than via the tiny doorway, there's no way to reach this other world -- there's no way to go there by conventional means. So it's not like one side could invade the other and ravage their resources.
Makes me wonder if there isn't some other secret way, or if they're all just worried about factions popping up trying to dominate both worlds. You already have one that has been devastated (seemingly at least) by a pandemic, so trust will be low. One could easily suspect the other of giving false info while trying to reap the benefit of good info they got from the other side before they can check and make sure they're receiving legit information in return.
