Our Straits Exchange Foundation and the Mainland's Association for Relations Across the Taiwan Straits (ARATS) had on April 26, 2009 entered a "Cross-strait Joint Fight against Crime and Mutual Legal Assistance Agreement", with the said agreement to take effect on June 25 of the same year. Pursuant to the Order of the Ministry of Justice dated August 10, 2009 under Fa-Jian-Zi No. 0980803292, the Bureau was authorized to establish official liaison channels with Mainland China's Public Security Ministry, Supreme People's Procuratorate, Ministry of Justice and the People's Bank of China's Anti-Money Laundering Bureau and Chinese Anti-Money Laundering Monitoring and Analysis Center, with the Bureau's Economic Crime Prevention Department undertaking secretariat work. Where the Bureau's subordinate units are required to conduct cross-border investigation of criminal activities they would be required to seek assistance from the Mainland law enforcement authorities through the Bureau's Economic Crime Prevention Department.
To maintain national security and protect the people, as well as effectively tackle cross-border criminal activities, thus fostering peace and stability across the Strait, the Bureau had engaged in cooperation and exchanges with law enforcement authorities in the Mainland, Hong Kong and Macao. Periodic visits were conducted annually for the exchange of information, joint investigation of cases, repatriation of convicts and suspects in criminal cases, reception of prison inmates, giving briefing on restrictions on personal freedom of Mainland Chinese in Taiwan, exchange of criminal investigation authentication skills, mutual visits by officers from both sides and convening of academic forums, seminars and conferences, thereby fostering mutual trust, both sides' understanding on joint-action against criminals and liaison channels, as well as enhance their professional ability to investigate cases.
