OSLO, June 25 (Reuters) - Norway's $1 trillion wealth fund can invest again in miner Rio Tinto (LON:RIO) RIO.AX and retailer Walmart (NYSE:WMT) WMT.N after their exclusions from the fund's investments on ethical grounds were revoked, the board of the central bank said on Tuesday.
The fund can also resume investing in Grupo Carso GCARSOA1.MX of Mexico, U.S. listed General Dynamics (NYSE:GD) GD.N and Canada's Nutrien NTR.TO , the board added in a statement.
Reinvestments will likely take place "within an appropriately long timeframe," said the board, without specifying a timeline.
