CBH chief executive officer Dr Andrew Crane has been appointed a member of the B20 Leadership Group.
The B20 is a forum through which the private sector produces policy recommendations for the annual G20 meeting of international finance leaders.
Dr Crane said he was honoured that Prime Minister Tony Abbott invited the CBH Group to play a role in B20.
"As members of B20 Australia, we will lead business engagement and co-ordinate the communication of international business priorities to the G20," Dr Crane said.
The CBH Group is the only participant on the B20 Australia Leadership Group, which is chaired by Wesfarmers CEO Richard Goyder, representing the agriculture industry and the first to represent co-operatives at B20.
"It is so important that the agriculture, agribusiness and co-operatives have a voice in this discussion," Dr Crane said.
"We have a key role to play in advising governments on priorities for our sector."
"It's great to have a strong WA voice leading these discussions. We have a great opportunity to focus government to government discussion on topics that support trade, engagement and industry growth through advising the G20," Dr Crane said.
The B20 meetings involve a series of discussions and workshops building up to the November G20 Leaders Summit in Brisbane.
This year the B20 will focus on four key policy areas: financial growth, human capital, investment and infrastructure and trade.
The November G20 Leaders Summit will take place in Brisbane.
G20 leaders meet annually to discuss ways to strengthen the global economy, reform international financial institutions, improve financial regulation and discuss the key economic reforms that are needed in each of the member countries.
