They condemned Syrian President Bashar al-Assad for his disregard for human life and agreed not to allow the use of chemical weapons to continue.
Macron said earlier this week that France was ready to attack the "chemical capabilities" of the Assad regime.
Unlike the last big wave of industrial action in 1995, when the government made an embarrassing U-turn, Macron seems determined to press ahead.
But the international body charged with independently verifying the deadly attack, the Organization for the Prohibition of Chemical Weapons (OPCW), has not been given access to the site of the alleged chemical attack in Douma.
"What they're probably searching for is: What can we destroy that weakens this guy?"
Russia, which backs Mr Assad, has softened its initial threats to retaliate against US ships and bases in event of an attack.
Macron went on national television TF1 Thursday to defend his efforts to transform the way the French work.
This is in contrast to an incident one year ago in which U.S. intelligence agencies had video and other evidence of certain aspects of the actual attack, which involved the use of Sarin gas.
"[Their] close military co-operation will not be a 50/50 balance", he says. "We intuitively share the feeling that the bond between the Church and the state has been damaged, and that both you and I need to repair it", Macron said. That strike did not appear to have had the desired effect of deterring Assad from further use of chemical agents.
The memoranda of understanding cover sectors including petrochemicals, water treatment, tourism, health, agricultural and cultural activities, the French-Saudi business forum said in a statement.
Students at universities across the country have been shutting down or severely disrupting classes for weeks, arguing the changes are an elitist attack on France's egalitarian principles.
It is important to note that the three countries - namely Russia, Syria and Iran - have denied using chemical weapons when in fact all the pictures prove the contrary. It would be the mother of all deals.
What Syria needs is not a political solution-that is unrealistic with so many conflicting agendas.
Understanding the centuries-old patterns that characterise the tangled web of relationships in this complex region is the key to finding a solution to the seemingly intractable Syrian crisis. Right next to that, there is a France of [immigrant] neighbourhoods which live with difficulty, which is a little ghettoised.
The agreement was announced on Sunday morning by Syria's government and its ally Russia, just hours after toxic gases were allegedly released on Douma.
Pontier also called out growing religious tensions fermenting in the country and instrumentalized by some populist parties in France.
Macron could well succeed where his predecessors have failed.
The Russian Ambassador to the UN urged the US and its allies to refrain from military action against Syria.
The Syrian and Russian governments have dismissed the allegations and said the footage of anti-government activists was staged. Furthermore, his progressive abolition of the housing tax will compensate for the rise in the CSG.
