Britain's Prime Minister Theresa May announced Saturday she authorized her country's forces to conduct "precision strikes" alongside America and France against Syria in the wake of the chemical attack that left dozens of civilians dead this week.
"Ten days ago President Trump wanted the United States of America to withdraw from Syria".
Mr Macron, who tweeted a picture of himself in a meeting room with military and diplomatic advisers, said a debate about France's military involvement would take place in Parliament.
"We convinced him it was necessary to stay for the long term".
The allied operation comes a year after the USA missile strike that Trump said was meant to deter Assad from further use of chemical weapons.
He said that in order to find a lasting solution in Syria, "we need to talk with Iran, Russia and Turkey".
"We can not tolerate the trivialisation of the use of chemical weapons, which is an immediate danger for the Syrian people and for our collective security", Mr Macron said.

French travellers on Friday faced a third wave of rolling train strikes which appeared to be easing off despite determination from rail union leaders to oppose President Emmanuel Macron's reform plans.
"In addition we expect our regional allies and partners to take greater responsibility both militarily and financially for securing the region".
"He (Russian President Vladimir Putin) has understood it's not the case anymore".
"Of course they are complicit". He described the main aim as establishing "a strong deterrent" against chemical weapons use.
"The team is preparing to deploy to Syria shortly", the organization said Tuesday. "We will continue because the world around us is speeding up, going through great changes, and because our country must be able to choose its destiny and live better", he said. "With those strikes we have separated the Russians and the Turks on this".
In a statement, the ministry said it believed the base was where the Assad regime was keeping "chemical weapon precursors" stockpiled in breach of the Chemical Weapons Convention.
Macron's comments were widely interpreted as moving France closer to joining the United States in a possible military strike despite critics' worries about a reprise of France's participation in a 2011 North Atlantic Treaty Organisation intervention in Libya, which helped bring down ruler Moammar Gadhafi but threw Libya into deeper chaos.
