China has GNSS (BeiDou, plus plans for LEO) plus terrestrial navigation (eLoran) plus a fibre-based network for accurate timing:

Russia has a Loran-equivalent:
Most GNSS receivers you can buy use multiple systems anyway.
While receivers can handle the signals of multiple GNSS signals, it may not be legal to do so. In the US, the FCC only allows GPS and Galileo:

Other systems, and their frequencies, are not a priority for the FCC and so aren't approved for use. Not sure how it works in other jurisdictions, but this may effect things in equipment that has to be certified to certain standards (like aviation equipment needs to be certified).
Apple, Google, Motorola, virtually all use GNSS receivers that read signals from GPS, GLONASS, GALILEO, QZSS, and BeiDou.
What The FCC wants is to know if the chips are implemented in a way that makes them vulnerable to exploits. If GPS and GALILEO signals are jammed or weak, GLONASS and BeiDou can be used to submit false information and cause chaos.
I think it should be possible to turn them off at least.
Seems at least according to that, there is plenty of +10% interference of GPS in the east and south of the Baltic Sea.
Reliable navigation is such a pure net positive for humanity.

The Poles want the EU to spend more on the MIC. That is not a surprise.
All while Russia is unable to even take the whole of Donetsk and Zaphorizia.
The "Russia is weak" and the "Russia will go to Portugal" narratives happily coexist in the European press.
Just because Russia cannot do some things, that doesn't mean they cannot do others and be annoying, like disrupting the airline industry:

(Or interfering with other countries' elections.)
Weak now and weak forever are not the same thing.
Arnold Schwarzenegger was once a baby, but it would be silly to conclude that means he can't lift 50 pounds today.
Putin's current territorial ambitions in Ukraine can be traced back to the West's almost complete inaction when he invaded Georgia, Donetsk, Luhansk, and Crimea. A victory in Ukraine would be likely to reinforce the approach as a functional one.
All narratives can be used when appropriate, by the same media outlet and sometimes by the same journalist.
(The issue with Georgia and Ukraine was primarily NATO membership, which does not apply to Poland or the Baltic states.)
"Russia is currently weakened by their war of attrition in Ukraine. Allowing them to win in Ukraine will embolden their territorial ambitions and permit them to rearm. As such, sanctions and aid to Ukraine must continue, to ensure they receive a solid lesson that will prevent them from future ambitions on EU territory."
Either someone jams GPS signal or they don't. The researches have some evidence that the former is true, so we need to gather more data (or decide that GPS jamming is not a problem - the less likely option).
