there exists/it exists

[Rilwen]

In a formal document by some world-renowned institution I've found the following phrasing:
"The reports clarify that it exists a relationship between ..."

I would say "there exists" instead of "it exists". If the latter is correct, are there any differences/rules how to use it?

Again, many thanks for your help,
R.

You are right. The report appears to be using unnatural English.
