As leaders of the 20 top and emerging world economies met in Antalya, Turkey, most of the talk was about security following last week's attack in Paris that killed at least 129 people. But the summit was called for economic discussions. In their final communique on the global economy, the world leaders:

—noted the global economy is growing unevenly and performing below expectations.

—cited risks from geopolitics and uncertainties in financial markets.

—pledged to stimulate demand and reiterated a commitment to lift GDP in the G-20 countries by 2 percent before 2018.

—promised to implement sweeping changes to international rules that could end tax-dodging by powerful multinationals. The changes reflect a plan released last month by the Organization for Economic Cooperation and Development.

—agreed to focus on youth unemployment and reduce "the share of young people who are most at risk of being permanently left behind in the labor market by 15 percent by 2025 in G-20 countries."

—noted that "2015 is a critical year that requires effective, strong and collective action on climate change and its effects," and called for an ambitious agreement when world leaders convene for a climate summit in Paris beginning later this month.

— called for a "coordinated and comprehensive response" to the global refugee crisis and called on all states to contribute.

— noted the threat to Internet freedom and commerce from cyberattacks and theft, and called on all states to "respect and protect the principles of freedom from unlawful and arbitrary interference of privacy, including in the context of digital communications."
