The friendship between Bill Clinton and Frank Giustra began a decade ago when the two met aboard Giustra’s private jetliner. Giustra says he was inspired by the former president's dedication to his philanthropic causes. The two have traveled often together, sometimes meeting political leaders in nations where Giustra has business interests. Here are a few highlights of their travels together.

January 2005
Clinton and Giustra first have contact when the former president speaks via satellite to a tsunami relief fundraiser organized by Giustra in Vancouver, B.C.

June 2005
When Clinton's staff asks to borrow Giustra's aircraft to fly the former president for a series of Clinton Foundation events, Giustra agrees on the condition he can join the trip. On their first meeting, the two men bond immediately. Between 2005 and 2014, Giustra’s jet is used in at least 26 foundation trips, with Giustra accompanying Clinton for 13 of them. 

September 3-6, 2005
Clinton and Giustra fly separately to Kazakhstan, where Clinton meets with the country's president to discuss charitable initiatives. The two join 50 others at a state dinner. Two days later, Giustra's company finalizes a $500 million deal to acquire three rich deposits of uranium in the former Soviet republic. The following year, Giustra makes a donation of $32.7 million to the Clinton Foundation. 

September 2005
Giustra, who has mining and other investments in Colombia, attends a Clinton Global Initiative meeting in New York City and has a first meeting with another attendee, then-Colombian President Alvaro Uribe.

July 2006
Giustra accompanies Clinton on a trip to Africa aboard his MD-87 jetliner.

May 2007 
Giustra helps launch a Canadian-based energy company that gets access to oil fields in Colombia. As it secured these leases, the Vancouver-based Pacific Rubiales' stock price soared.

2007
After talking for hours about how to effectively change conditions for the poor in Colombia and elsewhere, Giustra and Clinton agree to form a new arm of the Clinton Foundation -- the Clinton Giustra Sustainable Growth Initiative (CGSGI). An early donor: Pacific Rubiales Energy Corp., which pledged $3.5 million over the years.

Aug. 4, 2008
Clinton joins Giustra and Mexican businessman Carlos Slim, along with Luis Moreno, president of the Inter-American Development Bank, to announce new CGSGI projects in three countries, including Colombia.

June 8, 2010
Giustra and Clinton arrive in Colombia and are joined later by Secretary of State Hillary Rodham Clinton. She is scheduled to have an official meeting with Uribe, who has been pressing for passage of a free-trade deal. That night the Clintons and Giustra have dinner in Bogota.

June 9, 2010
Hillary Clinton meets with Uribe and expresses U.S. commitment to Colombia, including support for the free-trade agreement, a reversal of her previous position to one that coincides with the policy of the Obama administration.

Feb. 13, 2012
Giustra and Bill Clinton return to Colombia; Clinton participates in a Pacific Rubiales golf tournament that raises $1 million for the Clinton-Giustra charitable initiative. Two months later Hillary Clinton and President Obama travel to Colombia, where they announce a new free-trade agreement between the two countries.
