Cormann starts work at OECD with a double boost from Biden Save Share London | Former finance minister Mathias Cormann takes over the Organisation for Economic Cooperation and Development on Tuesday with a crucial global tax deal in sight and US President Joe Biden looking to beef up the Paris-based body into a bigger geopolitical role. Mr Cormannâs inner office will include Democratic Party heavy-hitter James Rubin, who has quit a senior lobbying job at Ballard Partners in Washington to become the new Secretary-Generalâs diplomatic adviser - a freshly created position that will help position the OECD at the centre of the Westâs strategic contest with China.
