So, go and ask Taiwan for unification. Strike a deal, give them rights, allow them to pay taxes.
The problem with Xi, is not his vision, but in his methods.
He has harassed Taiwan for more than decades. Throwing missiles over it's landmasses. Using maps claiming taiwan is in China's territory. Blockades, embargos, and threats of annihilation.
And it isn't like Xi couldn't turn this around, but every day he chooses to escalate tensions in the region rather then reaching for peaceful solution. It is clear his motives are not reunification. At least for the Taiwan people.
