Change is in the winds with the Universal Postal Union's third Extraordinary Congress in Switzerland in September 2019.

The playing field might get a little more level with China Post having to charge more for international postage as destination Postal Agencies (Australia Post) can now up their delivery prices.  However if China Post receives a postal subsidy from it's Government, that advantage goes out the window..  at least Australia Post will receive higher revenue, but hopefully won't inprove inbound delivery times for foreign mail.

"The Congress approved a proposal known as “Option V” by acclamation during its second day of discussions. The proposal will see the UPU accelerate rate increases to the system used to remunerate the delivery of inbound international bulky letters and small packets, phasing in self-declared rates as soon as July 2020".
