ANTALYA, Turkey -- The G20 summit concluded here Monday with broad consensus on ways of achieving inclusive and robust growth of the global economy, which is still recuperating from the impact of the 2008 financial crisis.

The major economies agreed to take measures to strengthen coordination of macroeconomic policies, promote trade and investment, stimulate employment and boost investment in infrastructure. These measures, if fully implemented, will give a powerful boost to slow economic recovery, analysts said.

The G20 leaders made a dim assessment of the global economic situation in a communique released at the end of their two-day summit in Antalya, a seaside resort in southwest Turkey.

"Global economic growth is uneven and continues to fall short of our expectations, despite the positive outlook in some major economies. Risks and uncertainties in financial markets remain, and geopolitical challenges are increasingly becoming a global concern," the communique said.

However, the G20 leaders said that they remain committed to lifting collective G20 gross domestic products (GDP) by an additional 2 percent by 2018, a target set in the last G20 summit in Brisbane, Australia.

Wang Xiaolong, the Chinese Foreign Ministry's special envoy for the G20 affairs, told reporters that against the backdrop of the sluggish global economic recovery, people have pinned high hopes on the summit, which is a primary forum for international economic cooperation.

"The summit sent a clear message...Although the global economy is experiencing some difficulties, we are still confident in the prospect of its medium-and long-term growth," he said.

The annual gathering of the G20 leaders also displayed the partnership among the G20 members, which is especially valuable at a time when the world economy is not in a good shape, Wang said, adding that the G20 leaders also agreed on a series of concrete measures to stimulate growth.

All of this will contribute to the achievement of a strong, sustainable and balanced growth of the world economy, he predicted.

With a possible interest rate hike by the US Federal Reserves in the coming months, the G20 leaders promised to "implement sound macroeconomic policies in a cooperative manner" to achieve a robust growth.

The anticipation of an imminent interest rate hike by the US Federal Reserves has sent shock waves across emerging economies in the world, whose currencies have weakened sharply against the US dollar in the past year.

"There is a clear need to continue a cooperative approach at the G20 level on global macroeconomic policies, with the aim of strengthening the recovery, lifting potential growth and enhancing financial resilience," said Donald Tusk, president of the European Council, in a statement.

In a bid to increase youth employment, the G20 leaders agreed to the goal of reducing 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 G20 countries.

The communique also showed that the G20 economies have developed ambitious country-specific investment strategies in order to boost much-needed infrastructure investment.

Citing an analysis by the Organization for Economic Cooperation and Development (OECD), the communique said these strategies would contribute to lifting the aggregate G20 investment to the GDP ratio by an estimated 1 percentage point by 2018.

In the communique, the G20 leaders pledged to work together for a successful Nairobi ministerial meeting on world trade and called for the prompt ratification and implementation of the Trade Facilitation Agreement.

The G20 leaders also agreed to step up the fight against corruption and plug tax loopholes exploited by multinational companies, as part of the efforts to enhance the resilience of financial institutions.

"The G20 represents 80 percent of the world economy, you can't make it happen in any other forum. Although the G20 is not a decision-making forum, but once a consensus is reached you can carry it forward wherever a decision has been made," OECD Secretary-General Angel Gurria said.
