Prime Minister Datuk Seri Najib Tun Razak announced this at a press conference Wednesday afternoon.
Najib also announced that three MCA vice-presidents were appointed as deputy ministers.
Datuk Paduka Chew Mei Fun is Deputy Women, Family and Community Development Minister, Datuk Chua Tee Yong is Deputy Finance Minister and Datuk Lee Chee Leong is Deputy International Trade and Industry Minister.
Chew and Lee will be made Senators.
"Representatives from MCA are returning to represent the Chinese community, and representatives from Gerakan are returning to the Cabinet," said Najib when unveiling the additions to the current line-up.
At the press conference, Najib agreed that there will be an increase in Cabinet portfolios due to MCA's re-think of its previous stance of not holding Cabinet posts after its performance in the 13th general election.
"We have to take into account the interests of all communities, that our promises to the people will be adhered to," said Najib.
He said he did not plan to have such a large Cabinet, but joked that "no one has volunteered to leave Cabinet."
Najib said the swearing-in ceremony would be conducted at Istana Negara before the Yang di-Pertuan Agong at 11.30am Friday.
