But by ordering his representatives to back out of the communique, Mr Trump appeared to be asserting his oft-stated aim of upsetting the status quo whether by pulling out of the global climate accord or the worldwide nuclear deal with Iran or threats to scrap the North American Free Trade Agreement.
Trump planned to leave the summit on Saturday before it discussed climate change and the health of oceans, underlining fractures in the G7 exacerbated by USA trade tariffs.
White House officials did not immediately respond to requests for comment on the characterizations by these officials of Mr Trump's remarks or attention to the presentations.
Despite Mr Trump's actions, the UK, France and Germany have insisted they will stand by the commitments made at the summit.
Mr Trump had earlier signed the joint statement agreed by all the G7 nations despite the trade row.
He also denied the summit had been contentious, a remark that contradicted what one G7 official described as an "extraordinary" exchange on Friday in which Trump repeated a list of trade grievances, mainly concerning the European Union and Canada.
"Russia is more often than not trying deliberately to be a strategic rival, to deliberately counter the good things we're trying to achieve in the world than for no other reason than to just counter them". Or we'll stop trading with them. He says the meeting was not contentious and that he gets along well with the other leaders.

In the ashes that remained they found thiophenes-relatively small and simple ringlike molecules containing both carbon and sulfur. The material was located in the first layers of rock, some four miles away from where the chlorinated molecules had been found.
Yesterday he added another item to that list - calling for Russian Federation to be readmitted to the G7 group of nations.
While the G7 chiefs have largely praised Trump for his efforts to stabilise the Korean peninsula, they are unhappy he pulled out of an global agreement created to limit Iran's nuclear ambitions. Several countries have said publicly they will retaliate against the US' new steel and aluminium tariffs with increased tariffs of their own.
While praising free trade in theory, Trump demanded an end to tariffs on US goods, which he called "ridiculous and unacceptable".
But his early departure means he will miss a working session among the leaders on climate change and clean energy, as well as talks among the G7 and poorer countries focused on the health of oceans.
"We had extremely productive discussions on the need to have fair and reciprocal" trade, he said.
He also said the USA was so disadvantaged it had nothing to lose in a trade war.
And while his bellicosity and volatility has deeply strained relations between the US and its historic allies, Trump insisted that he had terrific relationships with the G7 leaders, though before arriving at the summit he had unleashed a tweetstorm against some of them.
Speaking about Russia's military incursion in Crimea, a peninsula that was part of Ukraine, Trump on Saturday blamed President Obama for the annexation.
