Winston Peters is accusing Don Brash and Helen Clark of "relevance deprivation syndrome", after their criticism of his approach to China. 

The former National and Labour leaders are warning the Government that it could be putting our largest trading relationship at risk by aligning too closely with the US. 

Brash believes that it is unwise to shift priority from China to the US given the current tension between the two superpowers.

Peters says he stands by the government's independent foreign policy, and he sees no value in indulging in tired arguments from former politicians.
