"France's position is clear: full support for the security of Saudi Arabia, condemnation of the ballistic activity coming from the Houthis, willingness to find a political solution to the conflict and strong humanitarian demands on civilian populations", Macron said.
It follows news of a suspected chemical attack by Syrian government forces in a brutal assault on the rebel-held town of Douma that left more than 40 people - including children - dead.
Macron's response is swift and decisive on this matter related to Syria. Jean-Luc Mélenchon, leader of the far-left France Unbowed party, tweeted: "We expect a president, we get a little priest.' Lydia Guirous, of the conservative Republicans party, said Macron 'is playing a risky game and does not understand the republic".
The country, victim of the first extensive use of chemical weapons in military history during World War I, has long made combatting chemical weapons a priority. The finance ministry says it hopes the program, the improved deficit targets as well as the economic reforms led by the government will help France exit the excessive deficit procedure of the EU Commission.
The decision shocked the French, whose planes were poised for launch to participate in the operation. "Yet we are attached to the respect of global law and especially humanitarian law in Yemen".
After meeting with crown Prince of Saudi Arabia Mohammed bin Salman, the French leader announced that he will decide about the response of Paris after talks with his counterparts US President Donald trump and the Prime Minister of great Britain Teresa may.
Both men have played up their sound relations since Macron invited the American leader to attend France's Bastille Day festivities last July.
Earlier, Trump conferred twice on the telephone with Macron.
If Iran builds a nuclear bomb, "we will be in an extremely risky situation", the crown prince said.
President Emmanuel Macron has defended France's arms sales to Saudi Arabia which is engaged in a deadly war against its neighbor Yemen. France is already involved in the US -led coalition created in 2014 to fight the Islamic State group in Syria and Iraq.
Decisive joint action could give him leverage in arguing to uphold the deal, which comes up next for Trump's review on May 12.
French President Emmanuel Macron said that a decision on whether or not to carry out military action against Syria is being discussed between Washington, London and Paris.
