Papal trips: both “pastoral visits” and “state visits”
On his travels John Paul II took the advantages of being a visiting head of state and a religious leader, just as the Holy See exploits its dual status as country and church. He used his "state visits" paid for by his hosts, for "pastoral visits" where he evanglised at his World Youth Days, issued "moral guidance" on proposed laws and reined in "liberation theologians". Included is a list of the 104 trips of John Paul II. Another pope, Francis I, also has enough personal charisma to distract people from his conservative doctrines.
It was his predecessor, Pope Paul VI, who was the first to proclaim himself a ''pilgrim pope,'' but he made only nine trips abroad, occupying just 30 days of a 15-year pontificate.  By contrast, John Paul II, made reciprocal state visits a prominent part of Vatican diplomacy, with 104 trips to countries outside of Italy, which are listed below. (However, he did not always seem particularly welcome — in 1979, when he visited Mexico, then-President José Lopez Portillo pointedly referred to the Pontiff as "Sir." )
It has been argued that the rationale behind John Paul's travels was to counter the liberal reforms of the Second Vatican Council. They enabled him to evangelise at his World Youth Days at his hosts' expense, issue "moral guidance" on their proposed laws and rein in their "liberation theologians". These trips substituted the group excitement of huge public events for the stimulation of the new ideas of Vatican II, which were frowned upon by the Polish pope. He inaugurated World Youth Days, with papal appearances on a huge stage and much music. This enabled the media-friendly, but very conservative Pope to directly evangelise young people in their own idiom. John Paul's travels can be seen as a way to counteract the decentralising and liberal tendencies fostered by Vatican II.
Joaquin Navarro-Valls, the chief Vatican spokesman, said one of the Pope's major goals in traveling was to extend his personal authority and that of the papacy: "Early on, he realized he could not run the church from the Vatican". 
♦ The 1979 visit of John Paul II dubbed the "Hallelujah weekend of Ireland" coincided with that country's first tentative step towards legalising contraception. The pope devoted that trip to promoting "motherhood".
♦ On the eve of the Pope's 1982 visit to Britain, the Falklands War broke out. In order not to alienate the Argentines, the Pope quickly arranged to also visit Argentina. There General Galtieri, head of the military junta which was terrorising the country, received a papal kiss. These fast moving developments caught the Vatican off balance, which has left a rare record of political manoeuvring. 
♦ On his trip in 1985 to Peru he followed up on a document written by Cardinal Ratzinger condemning "liberation theology" which the Polish pope saw as Marxist, and demanded obedience from the Peruvian hierarchy. 
♦ In 1985 and 1990 he made two papal “pilgrimages” to the Ivory Coast. The first was to bless the foundation stone for a basilica and the second to consecrate the largest church in the world — an African dictator’s full-sized replica of St Peter's Basilica. The Vatican followed up three years later by concluding a very profitable concordat.
♦ His visit to Portugal in 2000 came just as the concordat negotiations were starting, a "treaty" which gave the Church a number of new privileges.
♦ His 2003 trip to Slovakia seemed to be timed to try to prevent parliament from legalising abortion and also to nudge along the negotiations for the "conscience concordat" before Slovakia joined the European Union.
♦ And his 1997 trip to Cuba prompted Cuba to declare Christmas a national holiday. Then in 2008 visit of his successor, Benedict XVI resulting in Good Friday being added, on a temporary basis , which in 2014 was finally made permanent.  Slowly, slowly....
The Iron Curtain came down in 1989, a couple of years before the pope was diagnosed with Parkinson's. Yet, in spite of declining health towards the end, he made frequent trips to the former East Bloc, visiting every country there at least once. There appear to be several reasons for his special interest in these post-Communist countries:
♦ to exert influence at a critical juncture when the institutions of these new societies were being formed, for example the initiative in Hungary which has resulted in most of that country's social services being administered by the Order of Malta. 
♦ to then use these countries whose national identity was Catholic to "evangelise from the east" the rest of Europe  ,
♦ to get these concordats in place before they entered the EU. The reason for this is that the ground-rules of the EU (Declaration 11 of the 1997 Treaty of Amsterdam) effectively protect church-state relations that are already in place from human-rights objections. In fact, the Vatican had to shelve the "conscience concordat" in Slovakia precisely because it didn't manage to get it through before that country joined the EU.
