The European Union's foreign policy chief has assured Jordan of continued financial support, saying it's an investment in stabilizing an ally in the "most heated and difficult area of the world."

Federica Mogherini visited Jordan just days after protests against proposed tax increases brought down the kingdom's prime minister.

Mogherini told a news conference in Jordan's capital Sunday that it's up to Jordanians how to carry out reforms, but that addressing tax evasion is key to a functioning economy.

Jordan is increasingly in debt and dependent on foreign aid, at a time when regional crises have helped drive an economic downturn.

Later Sunday, Saudi Arabia is hosting a meeting of Gulf Arab countries to offer support to Jordan. Gulf countries, once an important donor, haven't offered any funding this year.
