Citigroup is putting the final touches to its second big capital-raising effort in as many months, seeking up to $14bn from Chinese, Kuwaiti and public market investors.

Under the proposal being discussed, the bulk of the money – roughly $9bn – would be most likely to come from China, people familiar with the negotiations say. The Kuwait Investment Authority would contribute about $1bn, while $2bn to $4bn would be raised through a public placement of shares.
