The former UK monopoly said last week it planned to sell assets to slash its debt by 10 billion pounds (US$14 billion).
"BT has decided to focus on Western Europe and Japan, and as a result, will seek to realize the value of its investments outside those regions," said Harry James, a BT Asia spokesperson said in an interview.
A pullout by BT may be bad news for some phone companies in Asia which are counting on help from shareholders to raise money to pay for new licenses, expansion and improvement of networks.
BT owns 20 percent of Hong Kong's No 3 mobile operator SmarTone Telecommunications Holdings Ltd, 24 percent of Korea's mobile operator LG Telecom Ltd and one-third of Maxis in Malaysia. Maxis is not publicly traded.
BT also has a stake in StarHub Pte Ltd, Singapore's third mobile phone company.
"BT will be conducting a case-by-case study to realize the value in them, but as we speak today, there's no concrete plan for a sale in any one of those assets," said James.
James did not say when the evaluation will be completed. "There well may be other options" apart from selling, he added.
On Friday, BT shares declined 49 pounds, or 6.5 percent, to a three-week low of 700 pounds. They have fallen by half since the end of last year.
