Masayoshi Son, CEO of SoftBank, has been weighing up various options for chipmaker Arm after Nvidia walked away from buying the company.

Masayoshi Son, the CEO of SoftBank, said he is looking for a "strategic alliance" between Arm, which is owned by the Japanese company, and the South Korean company.

I plan to go to Korea. I'm going to visit Korea for the first time in 3 years. Son said in a statement that he would like to discuss a strategic alliance withSamsung.

There were no further details provided by SoftBank on what a strategic alliance would involve, but it could mark a big shift in strategy for Son.

When contacted by CNBC, SAMSUNG refused to speak.

Arm, one of the world's most important chipmakers, was acquired by SoftBank in 2016 and CEO Masayoshi Son has said that it is important for the company's long-term vision.

The deal to sell the arm to the chipmaker fell through in February.

The son wants Arm to be listed in New York. Arm is not allowed to list in the U.K. Following an initial public offering, SoftBank would like to keep a majority stake in Arm.

According to a report by The Korea Herald, Lee plans to meet Son when he comes to South Korea.

According to statements reported by The Korea Herald, Lee admitted that Son might come up with a proposal, but he has no idea what that is.

Many of the world's smartphones are powered by Arm's chip architecture.

Other companies have been linked with buying a stake in Arm. Amon said that the company is interested in investing in Arm.

Several companies are rumored to be part of a group that invests in Arm.

The Vision Fund, SoftBank's flagship tech investment business, posted a record loss in the last fiscal year. In the second quarter, SoftBank sold the rest of its stake in the U.S. ride hailing company.
