Three Asian Nations Top Passport Freedom Index

The firm says data shows that Singapore, Japan and South Korea have passports giving users most visa-free/visa-on-arrival freedom.
  Three major Asian jurisdictions - Japan, Singapore, and South
  Korea - hold joint top spot in an index for holding
  passports giving the most visa-free/visa-on-arrival freedom.
  
  According to Henley &
  Partners, a firm advising high net worth individuals about
  migration programmes such as “golden visa” systems, the trio
  chalked up a score of 189. 
  
  The Henley Passport Index is based on data from the International
  Air Transport Association and Henley & Partners itself. 
  
  Following a visa-exemption from Uzbekistan, Germany sits alone in
  2nd place, with a score of 188. Five countries now share 3rd
  place on the index, with a score of 187: Denmark, Finland,
  France, Italy, and Sweden. The UK, facing Brexit uncertainties,
  is now sitting in 5th place with a visa-free/visa-on-arrival
  score of 185, and the US in 6th, with a score of 184. 
  
  Afghanistan and Iraq remain at the bottom of the ranking with a
  score of just 30, a position one or both countries have occupied
  throughout the index’s 14-year history.
  UAE, Albania, and China rise
  The UAE continues its upward trajectory and is now just one spot
  away from entry into the index’s top 20. After the recent
  formalization of a mutual visa-waiver agreement signed with
  Russia, UAE passport holders are now able to access 165
  destinations around the world without a prior visa. This current
  score marks an extraordinary ascent from the position the UAE
  held a decade ago, when the country shared joint 61st place with
  Thailand and Zimbabwe and had a visa-free/visa-on-arrival score
  of just 52.
  
  Asia
  “With all Asian countries topping the index, there is a clear
  momentum behind the region taking centre stage in globalization.
  The steady rise of China through its visa-waiver agreements shows
  how incremental and reciprocal measures can lead to significant
  progress in trust and recognition,” Dr Parag Khanna, founder and
  managing partner of FutureMap and author of The Future Is
  Asian: Global Order in the Twenty-first Century,
  said. 
  
  Commenting further on the impact of China’s multi-trillion dollar
  Belt and Road Initiative, the largest infrastructure project in
  history, Dr. Khanna says, “With the Belt and Road Initiative
  expanding its constellation of member states and cross-border
  projects, we can fully expect Asian, European, Arab, and African
  countries to continue to seek more seamless access to each
  other’s countries. This will benefit both China and all states
  participating in the rising trade along the new Silk Roads.”
  
  Brexit headwinds
  While growing passport strength seems inevitable for some
  countries, uncertainty abounds for others, as protracted Brexit
  negotiations continue. 
  
  “Post-Brexit, it is likely that UK citizens will retain their
  (short-stay) visa free travel for the Schengen area. If the UK
  and EU manage to maintain a close political and trade
  relationship, the actual impact of Brexit on the travel freedom
  of British citizens may remain limited. However, the picture may
  change with regard to long-term mobility given that the free
  movement rights for UK citizens in the EU (and vice versa) will
  cease to apply,” Prof Dr Florian Trauner, Research Professor
  at the Institute for European Studies at the Free University of
  Brussels, said.
  
  A number of countries with “golden visa” programmes are in the
  higher reaches of the index, such as Malta, at eighth.
