SEATTLE - Canadian Prime Minister Justin Trudeau and Washington Gov. Jay Inslee met to discuss their close ties on topics ranging from trade to climate.

The two met briefly with local media Thursday before a private meeting at the Renaissance Seattle Hotel that lasted 45 minutes.

The prime minister arrived in the state Wednesday to attend and speak at Microsoft's CEO Summit in Redmond. The event, which was closed to the public and media, was focused on topics related to cybersecurity and the race to space. Trudeau's office said he is the first sitting head of government or state to be invited to address the summit and was there to promote Canada's technology industry.

Inslee said that Washington state and Canada share more than a common border, and Trudeau said they are "strongly engaged on issues of climate change, issues of openness to trade, leadership on refugees."

According to Inslee's office, the two discussed efforts to curb carbon pollution.

Both campaigned as climate champions. But protesters outside the hotel accuse Trudeau of betraying that trust last fall, when he approved the expansion Kinder Morgan Trans Mountain pipeline. It will link the oil sands in Alberta to a tanker port in British Columbia.

The pipeline will increase tanker traffic almost eight-fold through the Salish Sea.

According to Inslee's office, the two leaders discussed the efforts to protect the southern resident orcas, and Inslee offered the state's expertise on protecting Puget Sound moving forward.
