In January 1991, he became special correspondent for the
Ajker Kagoj. In September 1991, he became a diplomatic correspondent for the
Dainik Dinkal. In 1993, he became a correspondent for
Upali Newspapers of
Sri Lanka. In December 2003, Chowdhury was elected President of the ''Overseas Correspondents' Association Bangladesh-OCAB'' (Foreign Journalists Association) for 2004. He was the first Joint Secretary General of the Commonwealth Journalists Association (CJA), Bangladesh. Chowdhury was appointed
press secretary by President
Iajuddin Ahmed, serving from December 2004 to November 2006. On 13 November 2006, after President Ahmed took on the responsibility as
Chief Advisor of the
Caretaker Government, he appointed Chowdhury as one of his advisors, with the status of a
Minister of State.
Working with US and UN to stop martial law Chowdhury used good offices of the western diplomats led by the US Ambassador
Patricia A. Butenis and stopped the
martial law while the army group had to retreat to the option of the state of emergency, which was supported by all political parties for their own interests. Khaleda Zia with Moeen's support on 29 October 2006 made all the papers of the state of emergency. However, Chowdhury stopped the declaration of the emergency at night when the President Dr. Iajuddin Ahmed took over as the CA. Chowdhury was arguing through declaration of emergency the Army Chief would take over power. The AL led alliance was supporting the emergency from the beginning. At this stage, President Iajuddin declared a
state of emergency on 11 January and postponed the elections under the pressure of Moeen and his army group, as they would not be valid without full participation of the parties A group of military officers intervened to ensure stability, in what became called "One-Eleven." They established an interim government. In November and December 2006, Chowdhury worked with the US Ambassador in Dhaka Patricia A. Butenis, Under Secretary of State of the US Nicholas Burns called him from
State Department, Washington, D.C., he had talk with US
Assistant Secretary of State Richard A. Boucher and at Chowdhury's invitation UN Secretary General
Kofi A. Annan sent his emissaries to Bangladesh to stop martial law. Responding Chowdhury's all these initiatives Special Envoy Craig Jennes led a two-member UN delegation to Bangladesh and finally Patricia A. Butenis and
Anwar Choudhury met Principal Staff Officer General Jahangir Alam Chowdhury and Chief of Army Staff General Moeen U Ahmed, transmitted message not go ahead with their martial law option and informed if it happens Bangladeshi Peacekeepers will be back from the UN Peacekeeping Mission and there will be sanctions imposed on Bangladesh by the UN. Another message for army was to go back to barrack after restoring democracy holding parliamentary election within very short time, thus army rule's days were numbered. During 1994–1995, Bangladesh had a similar political deadlock, when the Awami League boycotted the 15 February 1996 election because no caretaker government had been established. In that event, negotiations had been led by the then-
Commonwealth Secretary General Chief Emeka Anyaoku's
special envoy Sir
Ninian Stephen. The violence and crisis in Bangladesh received international media coverage. In December 2006,
WikiLeaks leaked documents from Chowdhury's mission with diplomats, including
Patricia A. Butenis, as well as
politicians and other stakeholders on solving Bangladesh's political impasses, when they had worked together during the volatile political situation in 2006-07 period. The caretaker government struggled to hold elections within the constitutional 90-day deadline. The dates for the scheduled election were changed to 21 January, then 23 January, and finally 22 January 2007 in efforts to accommodate the political parties. Chowdhury had a series of meetings with stakeholders on governance and politics. With the help of United States envoys, he stopped the imposition of martial law planned by General
Moeen U Ahmed and his associates. ==Military intervention==
