JOHANNESBURG, Nov 4 (Reuters) - Finance chiefs from the Group of 20 will discuss eventually unwinding emergency economic stimulus packages introduced over the last year, U.S. Deputy Treasury Secretary Neal Wolin said on Wednesday.

"There will be a set of discussions about how we're going to sequence all this as governments think about moving from a period of stress and so forth to a period that's steadier and more regularised and as some of these extraordinary measures which the G20 countries took become less necessary," he said.
