South Australia wants to deepen economic and cultural engagement with China, using its strengths in minerals, energy, tourism and agriculture.
Premier Jay Weatherill and Manufacturing Minister Tom Koutsantonis launched the state's China strategy on Thursday which also stresses social and cultural links that have been fostered by migration and SA's 26-year sister-state relationship with Shandong.
"By 2030 China will be the world's largest economy - an economy that during the past 30 years has grown US$7.7 trillion," Mr Weatherill said.
"China's amazing pace of growth and continued urbanisation means its increasingly conscientious consumers are now looking to overseas markets to provide safe and reliable products and services."
Mr Koutsantonis said South Australia had a once-in-a-century opportunity to share in the growth of the world's most dynamic economic zone.
"South Australia must continue to raise its own profile in China so we can attract the capital investment that will underwrite our own prosperity well into the future," he said.
"We are in the right place at the right time with a growing reputation for providing world-class products and services to meet these demands."
The South Australian president of the Australia China Business Council (ACBC), Sean Keenihan, said the state's China strategy recognised the important role government played in supporting business engagement.
"Through the strategy's key initiatives, government will assist businesses by establishing the essential framework to optimise South Australia's engagement with China," Mr Keenihan said.
"Ultimately though, it is businesses that will deliver trade and investment outcomes and the ACBC encourages the business community to embrace this strategy."
Opposition trade spokesman Stephen Marshall said the government's China strategy offered no new ideas and no extra funding to boost exports.
"This is not a strategy. This is simply a plan to jump on the bandwagon of China's growth and to pretend that South Australian exports to the region are due to the government's glossy brochure," he said.
Mr Marshall said SA's exporters were well aware of market opportunities in China.
