Mitt Romney's upcoming international swing will provide the presumptive GOP nominee an opportunity to lend authority to his presidential bid, but it will not generate any new proclamations of policy, advisers to his campaign said.

Romney will travel to London, Israel and Poland beginning Wednesday, meeting with top leaders in each country for sessions meant to "learn and listen" rather than to advance any particular policy contrast with President Barack Obama.

The trip, Romney campaign policy director Lanhee Chen said, would be about "locking arms with our allies."

"We don't anticipate that this is an opportunity for the governor to make any specific policy pronouncement," Chen added, saying Romney would have an opportunity to make pointed foreign policy remarks when he addresses the national convention of the Veterans of Foreign Wars on Tuesday the day before he departs.

On his trip, however, Romney will come across some of the United States' most delicate diplomatic issues, which he has largely avoided speaking about in detail on the campaign trail in America. As a former businessman and governor, Romney will face the challenge of appearing presidential without any actual negotiating power. And his campaign will confront the logistical hurdles faced by presidents without the support structures that come with the office.

Romney's first stop is London, where Romney is slated to meet with virtually every major British political leader, including Prime Minister David Cameron, deputy Prime Minister Nick Clegg and opposition leader Ed Miliband. He will also meet with William Hague, the U.K. foreign secretary, and former British Prime Minister Tony Blair.

The U.K.-U.S. relationship, long considered the United States' most important bilateral alliance, will be a key stop for Romney given the two countries' shared economic and military interests. Romney foreign policy director Alex Wong said the GOP candidate "understands the significance of the relationship," and said Romney's trip there reflects his understanding of the partnership.

"Today as we face a number of fiscal and economic challenges around the world, a turbulent Middle East and Iran pursuing nuclear weapons, the U.S.-U.K. relationship is as important as ever, and this leg of the trip really highlights that theme," Wong said on a conference call previewing Romney's foreign swing.

Britain currently deploys 9,500 servicemen and women in Afghanistan, according to the website of the Ministry of Defence, and remains a key ally to the United States as the two countries prepare to withdraw troops from the country.

Romney has called an American plan to reduce troops earlier than the 2014 deadline "naïve" and "misguided," and says on his website he would formulate a withdrawal strategy based not on electoral politics but on the "conditions on the ground as assessed by our military commanders."

Cameron, a member of Britain's Conservative Party, said this week on a visit to Afghanistan there would be no "cliff edge" after NATO troops withdraw in 2014.

Romney, who mentions often on the campaign trail his leading role in the 2002 Salt Lake City Olympics, will be in London for the opening ceremony of the 2012 Summer Games. Ann Romney, the candidate's wife, co-owns a dressage horse competing in the games.

"This is a moment of pride for London, and the entire United Kingdom, so Gov. Romney is looking forward to celebrating this moment with the English people," Wong said.

From London Romney will travel to Israel, a staunch U.S. ally that Romney has made clear he would support as president. There, Romney will have several public events, according to his campaign, and will meet with officials including Israeli Prime Minister Benjamin Netanyahu, Israeli President Shimon Peres and Salam Fayyad, the prime minister of the Palestinian National Authority.

The former Massachusetts governor, who last traveled to Israel in January 2011, has had a long relationship with Netanyahu, as they both worked together at the Boston Consulting Group in the 1970s.

In an interview with CNN earlier this year, Netanyahu expressed admiration for Romney but did not go as far as making what could be considered an endorsement.

"I respect Mitt Romney as I respect Barack Obama, the president of the United States. And that's the end of the ranking," the prime minister said on CNN's "Erin Burnett OutFront." "I have enough politics here than to get into American politics."

On the trip, Romney "is looking forward to not only reconnecting with a number of leaders, but to listen and to learn. He feels strongly about the importance of locking arms with these leaders," according to Dan Senor, a foreign policy adviser to Romney's campaign.

Romney's visit to Israel will be his fourth, according to Senor. Previous trips included a visit with his family in the late 1990s and a four-day tour in January 2007, during which Romney participated in economic and security briefings.

Romney has used tough language when describing Obama's record on Israel. The candidate addressed the ongoing peace process at a CNN sponsored presidential debate in January, including the two-state solution that would result in an independent Palestinian state alongside Israel.

"There are some people who say, should we have a two-state solution? And the Israelis would be happy to have a two-state solution. It's the Palestinians who don't want a two-state solution. They want to eliminate the state of Israel," Romney said. The debate was held in the heat of the GOP primaries.

Romney continued: "The best way to have peace in the Middle East is not for us to vacillate and to appease, but is to say, 'We stand with our friend Israel. We are committed to a Jewish state in Israel. We will not have an inch of difference between ourselves and our ally, Israel.'"

In Poland Romney will meet with the country's president, prime minister and foreign minister, as well as visit historical sights.

Romney's stop in Poland came after an invitation from Lech Walesa, the shipyard worker who went on to inspire the Solidarity trade union and the eventual fall of the Iron Curtain. In 1989, Poland formed the first noncommunist government in the Soviet bloc, and Walesa later was elected president. Romney will meet with Walesa in Gdansk.

In May 2011 Walesa declined to meet with President Barack Obama, telling Agence France-Presse the meeting "would only amount to a photo opportunity."
