From comments on global trade, the depreciation of the dollar and women's rights, the World Economic Forum has made headlines once again. CNBC takes a look at the most memorable quotes over the past few days from the snowy Swiss Alpine resort of Davos.

President Donald Trump's speech was the most widely-anticipated moment at this year's event. It was the first time since Bill Clinton in 2000 that a sitting U.S. leader has joined the Davos elite. He told the audience: "We cannot have free and open trade if some countries exploit the system at the expense of others." Earlier in the week, Trump told CNBC that "the dollar is going to get stronger and stronger, and ultimately I want to see a strong dollar." A sharp weakening for the greenback on Wednesday was one of the main discussion topics at Davos, following comments from U.S. Treasury Secretary Steven Mnuchin.

Mnuchin sparked fluctuations in currency markets when saying that a weaker dollar is good for the U.S. During a CNBC panel on Thursday, the U.S. treasury secretary said that dollar weakness in the short term was "not a concern of mine." He added: "In the longer term, we fundamentally believe in the strength of the dollar."

Emmanuel Macron

Praised by many in the business community, French President Emmanuel Macron vowed to reform France and Europe with a medium-term strategy, in order to provide clarity to investors. "Let us not be naive, globalization is going through a major crisis and this challenge needs to be collectively fought by states and civil society in order to find and implement global solutions," Macron said during his keynote speech.

Germany is currently going through a political impasse — something that Europe wants to see fixed very soon in order for it to move forward with more integration. Speaking at Davos, German Chancellor Angela Merkel admitted that Germany has problems of its own. "Frankly speaking, the country I have the honor to represent and where I am chancellor has difficulties. And polarization is something that we see in our country as well, which we haven't had for decades," she said.

Narendra Modi

Indian Prime Minister Narendra Modi spoke about a "worrying trend" against globalization and towards isolationism. "Forces of protectionism are raising their heads against globalization, their intention is not only to avoid globalization themselves but they also want to reverse its natural flow," he said.

Billionaire investor George Soros believes that the U.S. is on course for a nuclear war with North Korea. "The fact of nuclear war is so horrendous that we are trying to ignore it, but it is real," Soros said during a speech on the outskirts of the World Economic Forum. "Indeed, the United States is set on a course towards nuclear war by refusing to accept that (North) Korea has become a nuclear power."

Lloyd Blankfein

The policies of the U.S. president were under scrutiny, but not everyone is unhappy with the direction Trump is taking. "I'd say I like a lot more stuff than I don't like, and some of the stuff I don't like I really don't like," Lloyd Blankfein, CEO of Goldman Sachs, told CNBC during an interview. "But I don't want to be hypocritical, either. I've really liked what he's done for the economy," he added.

The youngest Nobel Prize laureate and activist for education told the World Economic Forum that the only way to ensure women's rights is by educating young boys. "The education of young boys on the subject of women's rights is crucial. When we talk about feminism and women's rights, we are talking to men. We have to teach young boys how to be men," Malala Yousafzai said at Davos.

"Even without testosterone, we can produce positive, constructive energy," the Managing Director of the International Monetary Fund Christine Lagarde said in Davos. Lagarde was one of seven female co-chairs at this year's forum, drawing attention for women's rights, including equality in the workplace.
