Both countries are involved in a US-led coalition battling against Islamic State jihadists in Iraq and Syria.
The two nations are the only Arab monarchies who do not belong to the oil-rich Gulf Cooperation Council, closed to outsiders since its creation in 1981. But both kingdoms were invited to join the six-member club in May 2011 in the midst of the Arab Spring uprisings.
The move was welcomed by Rabat, which nonetheless reiterated its "natural and irreversible commitment" to building the Arab Maghreb Union (AMU) to strengthen economic cooperation between several North African and Sahel countries.
Under the new rapprochement with the GCC, a strategic partnership was signed in late 2011 to finance development projects in Morocco and Jordan worth more than $5 billion.
The Moroccan king travelled to Jordan in late 2012 as part of a regional tour.
