Scores of Afghan migrants marched through the streets of Stockholm on Friday in protest over President Ashraf Ghani's comments during a Germany TV interview where he said if Afghans "live abroad they become dishwashers."

Demonstrators, who marched to the Swedish Parliament, also raised their objections over a possible agreement between Afghanistan and Sweden to deport Afghan migrants.

They said if government comes up with solid security measures and if high-level government officials bring back their own families that live abroad they will be prepared to return home.

During his interview with Deutsche Welle on Thursday, Ghani urged Afghanistan's elite to make the most of opportunities at home rather than moving abroad.

"The privileged elites are part of the globalization moment that we live in. What is significant is to create opportunities for the generations to come. If the families of the privileged live abroad they are not going to have careers abroad. Their careers are back in Afghanistan. (...) If they live abroad they become dishwashers. They don't become part of the middle class."

Ghani himself, however, did rather well when living abroad in the United States, completing a doctorate in anthropology and becoming a professor at Johns Hopkins University before returning to Afghanistan after the fall of the Taliban.

Confronted with this fact, Ghani said: "The minute opportunity was created in 2001 I returned. I hope that the new generation of our friends will have the same sense of patriotism and respond to the conditions of our country."

However, Afghanistan and Sweden agreed to open talks on repatriating Afghan nationals whose asylum bids have been rejected, leaders of both countries said.

Addressing a joint press conference following high-level talks with his Swedish counterpart, Ghani said: "Migration is a human tragedy and a human phenomenon. As partners we have agreed there is a common problem."

Swedish Prime Minister Stefan Lofven said: "Many refugees coming to Sweden are from Afghanistan or Afghans, many are unaccompanied minors."

"This year about 20,000 minors, primarily young men, have come to Sweden, and this is of course a serious challenge for both our countries."

The two sides were also to review the reasons contributing to the migrant flows.

These include poverty, insecurity and lack of trust. "We will address the push factors," Ghani said, also pointing out that a significant number of Afghans had arrived from "third countries."

Local media also reported that during Ghani's visit, a new bilateral aid agreement was inked. Lofven underlined that Afghanistan remained Sweden's main foreign aid recipient and was set to receive about $1 billion dollars in the period 2015-2024.

The two also discussed security issues in Afghanistan, with Ghani paying tribute among others to the 10,000 Swedish nationals who served with the NATO-led Resolute Support Mission in Afghanistan.

According to Lofven, Sweden had been forced to tighten asylum rules as it was struggling to provide accommodation for all arrivals. His country had received 80,000 asylum applications over the past two months, equaling the total for the whole of 2014, he said.

Last week, Sweden announced it would tighten rules for asylum seekers and no longer give permanent residency to all people granted refuge.

The government on Friday also presented a draft bill that would give it emergency powers to temporarily close roads - but not railways - to the country on "security" grounds.

This could allow the government to close vehicle traffic for up to a month on the Oresund rail and road bridge that links Sweden and Denmark.

Sweden - a country of almost 10 million - has along with Germany and Austria been among the top destinations in Europe for people fleeing conflict in countries such as Syria and Iraq.
