West Australian Premier Mark McGowan will travel to Beijing this week for meetings with representatives from government and business.
Last month, the premier defended spending more than $250,000 leading a delegation to China and Japan in November, saying it was a worthwhile 10-day trip to promote the state and secure jobs.
Sixteen people, including ministers and bureaucrats, spent almost $120,000 on airfares, accommodation and "associated costs", and more than $118,000 on expenses in China alone.
Mr McGowan will visit Beijing for the first time as premier from Wednesday to Saturday.
"China is Australia's biggest trading partner and I want to ensure that WA is in the box seat to maximise opportunities that will create more jobs in the resources sector, as well as industries like tourism and education," he said in a statement on Sunday.
"The benefits from the visit last year are already starting to flow, with a new strategy launched to promote Perth as a study destination and positive discussions about direct flights from Shanghai."
