Malcolm Turnbull disappointed G20 pioneers did not denounce North Korea

Prime Minister MalcolmTurnbull has expressed his disappointment that G20 leaders failed to condemn North Korea's provocative ballistic missile tests.

But Mr Turnbull said that "nobody round that table was defending the North Koreans, in terms of their conduct" at the G20 meeting in Hamburg.

And after discussions on Saturday evening with French President Emannuel Macron at the Elysee Palace, the Prime Minister said he was confident that Australia would begin construction on the next generation submarine from 2021.

President Macron said on Saturday night, at a joint appearance with Mr Turnbull, that France would do "everything necessary" to keep its end of the bargain and deliver Australia 12 new submarines on time.

Mr Turnbull also said Australia "regretted" the US decision to pull out of the Paris climate deal, "but apart from that there is considerable agreement and consensus on the climate and energy issue".

"As far as North Korea are concerned the chair of the G20, Chancellor Merkel, made the point that the G20 has been historically largely an economic conference  there is unanimous condemnation of the conduct of the North Korean regime," he said.
