Jacinda Ardern hasn't been able to change Joe Biden's mind about the CPTPP free trade agreement.

The Prime Minister has met the US President at the White House this morning.

The pair discussed trade, China's growing influence in the Pacific, and New Zealand's experience on gun control.

Ardern says the meeting was focused on discussions, rather than changing of minds.

“Our meeting was very much focused, not on announceables, but on furthering and deepening the relationship and we have absolutely done that.”

Ardern was trying to convince Biden, to get the US back in the CPTPP.

Chief Political Reporter Jason Walls told Mike Hosking her efforts don't appear to have worked.

“If she’s sitting in the  room with Joe Biden, who was keen on it before, and she still can’t get him over the line, it’s just not going to happen.”
