Burmese President Thein Sein is promising to release all political prisoners in his country by the end of this year.
Mr. Thein Sein made the pledge Monday during a speech in London as he visited Britain for the first time.
He was given a warm welcome by British Prime Minister David Cameron. The two leaders discussed increasing trade links and military cooperation. Mr. Cameron also urged the Burmese president to defend human rights.
President Thein Sein said thousands of prisoners already have been released from Burma's jails. He said a committee is working through the cases of those still in prison.
The Burmese leader also said he is close to brokering a nationwide cease-fire to end long-running conflicts between the government and various ethnic groups.
Mr. Thein Sein's visit was met by some protestors in London who demonstrated against Burma's human rights record.
