Tuvalu citizens offered Aus refuge

This week's announcement by the PM that Tuvalu
citizens impacted by rising ocean levels due to climate
change will be accommodated in Aus. This, IMO,
is a very important announcement.

But if I were China, I would offer "island building" services
to lift the height of the Islands (similar to China's island building
in the China Sea) As such the natives could stay at home
enjoy Chinese "welfare"

But China would likely demand a caveat:
-an extended airport
-a fishing port & infrastructure
