Treasurer Joe Hockey will urge his G20 counterparts to stick to the promise of raising world growth by an additional two per cent over the next four years.

Mr Hockey is heading to Turkey on Wednesday for a G20 finance ministers meeting in Ankara to discuss the most recent global events and will remind them of the historic growth agreement made in Brisbane last year under Australia's presidency.

"All countries must take all possible steps to lift growth and achieve this target and Australia is playing its role too," he told reporters in Sydney.
