China's Belt and Road initiative is a scheme to promote closer ties between countries through trade – it has a large infrastructure element.
The focus on infrastructure had been a sticking point for Peters in the past.
"We are increasingly a branch economy of China. One belt, one road but so many unanswered questions," he said in a speech in May 2017, before he became Foreign Minister.
But today, Peters said Parker had made it very clear the Government wants to know in detail and with clarity, "what it all meant."
"They are still working on it – that's what he [Parker] made very clear."
Speaking to media before going into the House this afternoon, Parkers said the framing of Belt and Road, from China, had broadened "as of late".
"It's no longer just about infrastructure – it can cover other areas of co-operation."
In fact, China's President Xi Jinping said at the forum that he wanted "open, green and clean co-operation" with "zero tolerance for corruption".
Prime Minister Jacinda Ardern also said that the thrust of what Belt and Road was about had changed.
She said strategically, there has been a view that belt and road was simply about strategic infrastructure but the belt and road initiative had evolved over time.
"We welcome foreign direct investment as beneficial to New Zealand and that's equally what we're looking for through those initiatives."
She said the focus on the Belt and Road only being about strategic infrastructure has been broadened out, over time.
