Becos they think China can't do without Australia goods. They are break away from reality the world is ever changing. Their arrogant attitude never change and must teach them a lesson.Honestly, I just do not know why these Government and Opposition politicians here would deliberately destroy Australia - China trade relationship because it a very lucrative trade for Australia. Thousands of jobs are tied up with this trade, and it is going to have a massive impact on unemployment if these idiots continue to push their agenda.
