Anderson and fellow Yes alumni keyboardist Rick Wakeman and multi-instrumentalist Trevor Rabin have been touring as ARW over the past year or so.
Howe said during a recent Q&A with fans via Yes' official website that there currently isn't much communications between Yes and ARW.
"As far as I understand, ARW aren't really interested, and we're most probably not either," said Howe before offering some optimism. "Now, that sounds like a big shutdown -- but things aren't always what they appear."
He acknowledged that there could be some common ground on which the group could stand.
"I think there's ways that we can celebrate Yes; 50th year, and most probably that want to as well. Those things aren't easy -- it's not any one person that's particularly making it difficult. But people can make it difficult. And then it's got to be done in the right spirit."
Yes was formed in 1968 by Anderson and late bassist Chris Squire, who passed away last year.
