May 15 (Reuters) - UK's BT is reviving talks over

a possible sale or partnership of its struggling international

business a year after halting negotiations, Sky News reported.

Britain's largest telecom group plans to rekindle talks with

companies such as AT&T ( T ), Orange and Verizon

, the report said.

Here are some details:

* The sale will be part of BT's strategy to refocus on the

domestic UK market where it has been losing customers to smaller

rivals, pushing CEO Allison Kirkby to optimize its resources.

* The reported discussions come over a year after BT

unveiled plans to create a separate international unit following

media chatter around partnership talks with AT&T ( T ) and Orange.

* Last year, BT divested its financial information business,

Radianz, in a bid to optimize its international business.

* The international unit, which includes operations in

countries such as Argentina, Brazil and Canada, is currently led

by Clive Selley, the former boss at BT's other major business

Openreach.

* Lazard or Goldman Sachs are expected to work with BT on

the talks, the report added, citing industry sources.

* BT declined to comment on a Reuters request for comment.

* AT&T ( T ), Orange and Verizon did not immediately respond to

Reuters' requests for comment.
