The Chinese government has no obligations to non-citizens. You are on your own if you give up your Chinese citizenship.
Perhaps, but what about protecting state investments? Those were Chinese state funds which invested in Natures Own and what the Australians did was no different to a CIA backed terrorist trying to disrupt BRI or US forces stealing Chinese aid and passing it off as their own to Palestineans.
This Chinese Taiwanese family, in an effort to perhaps beg mercy from the anglos, went ahead and destroyed the company and pushed the debt into the Chinese state funds. That matter deserves its own justice, the issue here is the Australasian government is trying to exercise jurisdiction over Chinese state funds. Given that the anglos demonstrably only respect strength and power, it would be to the benefit of the Chinese people for such a ”Wagner” style PMC in the pacific.
More importantly, a lesson must be sent out to the Rhodesia of the pacific that they are guests who live at the pleasure of their Asian neighbours. These people only respect 'Rules Based Order' of strength, let them respect Chinese strength instead.
In fact, going back to the above theme, i see this example with the Australians as a microcosm of China's ascension in the fact of the declining Anglos. Much as China will never be left alone and allowed to develop in peace, no successful Chinese entrepreneur will be allowed to do business in peace unless the local government is influenced by Chinese forces. White Christian Russia wasn't even allowed to develop in peace so why would the Anglos behave differently to a "upstart yellow menace"?
