You know, disagreements over little issues like human right violations in Cuba and the Castro brothers' insistence in poking their noses in South Pacific affairs, which makes the Australians understandably nervous.
Still, it was a little surprising to see the following headline in this morning’s edition of The Sydney Morning Herald: “Cuba slams Australian critics”.
After all, despite the very close relationship between Canberra and Washington, Australia was one of the nations that voted at the United Nations this week in favour of lifting the American trade and commercial embargo on the island.
So what's the problem?
Well, the Australian ambassador at the UN, Robert Hill, used the opportunity to call on the Castro brothers to do the right thing at home by freeing political prisoners and respecting human rights.
Mr Hill said that supporting moves to lift the commercial embargo should not be seen as endorsing the Castro regime's internal policies, adding: "Holding political prisoners and failing to comply with international human rights standards is not an internal matter - it should be of concern to all of us."
The response from Havana wasn’t long in coming. A spokeswoman is quoted in the Herald as saying: "A government like Australia has no moral authority to criticise Cuba."
I beg to differ, miss.
