The agreement also included promises to ease visa restrictions for Turkish citizens, revive Ankara`s EU accession negotiations and strengthen the customs union between the two sides. The Turkish government has argued that Brussels has not complied with the agreement on these issues, even though it has fully implemented itself. Klaus Schwab, founder and executive chairman of the World Economic Forum, said in January 2016 that the refugee crisis could be the precursor to something more important. Bloomberg summed up his comments as follows: the BBC used the term “migrant” to represent all those travelling during this period, in its critical articles published in 2016 “Migration Crisis: Declared Migration in Europe” and 2015 “Migration Crisis in Europe”.  According to the BBC, the crisis included people who had not yet applied for asylum, refugees and economic migrants.  Afghan refugees are the second largest refugee population in the world.  According to UNHCR, nearly 2.5 million Afghan refugees have been registered. Most of these refugees have fled the region because of war and persecution. The majority have settled in Pakistan and Iran, although it is increasingly common to migrate west to the European Union. Afghanistan has faced more than 40 years of conflict dating back to the Soviet invasion of 1979. Since then, the nation has faced fluctuating civil wars amid endless turmoil. The increase in the number of refugees is mainly due to the presence of the Taliban in Afghanistan. Their withdrawal in 2001 led nearly 6 million Afghan refugees to return home.
However, nearly 2.5 million refugees have fled Afghanistan after riots and fighting in addition to the return of the Taliban.  However, most Afghan refugees seek refuge in neighbouring Pakistan. However, more and more people have committed to migrate to Turkey and the European Union. January 27, 2016 The European Commission accused Greece of neglecting its obligations under the Schengen agreement to control external borders and said that a visit by EU inspectors in November 2015 revealed that Greece had failed to correctly identify and register arrivals, that it had taken all fingerprints and verified travel documents, and that it was verifying authenticity and security databases.  On 12 February, the EU set Greece a three-month deadline to set its border controls or other Member States could be allowed to extend border controls for up to two years instead of the usual six months.  The junior coalition`s partner, Vice-Chancellor Sigmar Gabriel, said Germany could take in 500,000 refugees a year over the next few years.  German resistance to the government`s reception of the new wave of migrants has been strong and has been associated with an increase in anti-immigration protests.  Pegida, an anti-immigration movement, briefly flourished at the end of 2014, followed by a new wave of anti-immigration protests in late summer 2015.  Merkel stressed that Germany was in favour of economic strength to cope with the influx of migrants and reiterated that there was no legal ceiling for the number of migrants Germany can take in.
 In September 2015, enthusiastic crowds welcomed refugees and migrants arriving across the country.  In November 2016, the Euro-Mediterranean Human Rights Monitor published a report on the humanitarian situation of migrants in Greece.
