Britain's Financial Times reports that SK, the largest mobile service operator from South Korea is going to spend about US$100 million to acquire 10% of China Unicom (CHU).

China Unicom is the second largest mobile service operator in China.

The report says that SK is in contact with bankers and it is expected to soon choose one consultant from among them.

However, analysts quoted in local Chinese media are suspicious of SK's investment in China Unicom. They say that the prospects of China Unicom are not so clear, and SK may not gain any decision-making power despite how China Unicom might be restructured in the future.

China Unicom and SK have not made any comment on the report.
