The New Zealand initiated Security Council meeting on Syria has ended without any new agreement on a way forward, although John Key believes a resolution built around the recent ceasefire is still possible in time.
The meeting was dominated by a fiery speech from a clearly frustrated US Secretary of State John Kerry.
In it Mr Kerry lashed out at Russia over the Syrian peace process, saying at times he thought Russia was operating in a "parallel universe".
Mr Kerry questioned why rebel groups that are fighting the Russian backed Assad government would want to sit at the table and talk, when the regime "bombs hospitals and drops chlorine gas again and again and acts with impunity".
He took particular issue with Russia's response to the bombing of an aid convey two days ago that killed 20 people in Aleppo, questioning why it has repeatedly changed its position.
He also pointed out that the only groups capable of flying at the time of the bombing were either Syrian Government or Russian planes.
Russia denies being behind the bombing and its Foreign Minister Sergi Lavrov told the Council that an investigation into the bombing was needed.
Mr Key who was chairing the Council in New Zealand's capacity as President, says while the process is a "bit two steps forward and one step back and a little bit of finger pointing", everyone came back to the same view that there isn't another way forward other than the cease fire that was put in place a week ago.
He believes there still is a willingness to find a solution and it was encouraging that a special group on Syria, involving the US and Russia, planned to have another discussion on the issue on Saturday.
Mr Key says today's meeting was the starting point not the ending point and a resolution was still possible.
In what was perhaps the main new suggested action from the meeting Mr Kerry proposed that aircraft in conflict zones be grounded as a way of restoring credibility to the damaged ceasefire process.
