As far as I know, the European Commission never gave an answer to this question raised directly by Chinese officials.
I guess it was hubris, and " what can you do about it even if I poke you in the eyes " attitude, because the Europeans simply did not believe China could build their own system by herself ahead of the Galileo.
Now we know better, and indeed it is sweet revenge, haahaahaa.
I believe they both use the same frequency. As China was the first to use the frequency, she had the right to not let Galileo use it?

Yes, China has the right to the contested frequency since she got there first, and of course Europe would not let go that easily.
I believe the two sides have held several meetings to resolve the differences, and it seems both sides have accept a compromise of sharing the same frequency.
That means if USA wants to jam the Beidou, Galileo will be affected too, nice bundling together making Galileo a hostage .

(ITU) policies, the first nation to start broadcasting in a specific frequency will have priority to that frequency, and any subsequent users will be required to obtain permission prior to using that frequency, and otherwise ensure that their broadcasts do not interfere with the original nation's broadcasts. As of 2009, it appeared that Chinese COMPASS satellites would start transmitting in the E1, E2, E5B, and E6 bands before Europe's Galileo satellites and thus have primary rights to these frequency ranges.

I guess ITU policies of first come first serve were written to safeguard western interests, because western countries thought only they had the technological prowess to compete against each other, and never imagined that a non western country ( in this case China ) could ever steal a head start over Europe. So the ITU had no choice but to grant China the recognition and priority to use those frequencies.
I am sure the ITU policies would have been amended to European favor if the western countries knew China could be ahead, but then China launched her first Compass/Beidou satellites so rapidly that Europe had to concede it fait accompli.

Beidou accuracy, presumably civilian. Average global accuracy is 2.34m.

The head of the ITU also happens to be a Chinese national.
