Aerospace giant Boeing looks to have addressed a weakness that Airbus exposed last year, by proposing a joint venture with Brazilian plane-maker Embraer.

The deal's about regional jets, passenger planes with about 100 seats and ranges up to 5,000km. Neither Airbus nor Boeing make such planes – the former’s A318 and the latter’s 717 went out of production in the years 2013 and 2006 respectively.
