TOKYO (Reuters) - SoftBank Group Corp 9984.T founder and CEO Masayoshi Son said on Wednesday Saudi Arabia and Abu Dhabi are showing "high interest" in investing in the second Vision Fund.

Discussions are still continuing so Saudi Arabia and Abu Dhabi were not included in the list of participants pledging $108 billion to the fund announced last week, Son said at a news conference in Tokyo.
