They are a bipartisan group of senators who are sitting in the Armed services, and Foreign relations committees.Technically speaking those Senators don't represent the US Govt . Unless China has made an official policy of barring politicians across the World from visiting Taiwan then i don't see why China should be angry.
All i want is China to go beyond diplomatic protests. I read that China was ready to scramble jets when the UN Ambassador visit was planned. Why not do the same here and show that you mean business?
They are definetely not visiting by just their own decision. They obviously have approval from other people.
And this is serious because after these people visit then you would have the US dogs, EU Parliament, visiting it, then soon after, the whole world Parliaments would be visiting Taiwan
As I said, this is salami-slicing China's red lines
If China didnt have countermeasures for when that would happen then these Red Lines are the same one which Obama used on Syria...
