A diplomatic mission or foreign mission is a group of people from a state or organization present in another state to represent the sending state or organization officially in the receiving or host state. In practice, the phrase usually denotes an embassy or high commission, which is the main office of a country's diplomatic representatives to another country; it is usually, but not necessarily, based in the receiving state's capital city. Consulates, on the other hand, are smaller diplomatic missions that are normally located in major cities of the receiving state. As well as being a diplomatic mission to the country in which it is situated, an embassy may also be a nonresident permanent mission to one or more other countries.
The Taipei Economic and Cultural Representative Office (TECRO), also known as Taipei Economic and Cultural Office (TECO), Taipei Representative Office (TRO) or Taipei Mission, is an alternative diplomatic institution serving as a de facto embassy or a consulate of the Republic of China to exercise the foreign affairs and consular services in specific countries which have established formal diplomatic relations with the People's Republic of China. The PRC denies the legitimacy of the ROC as a sovereign state and claims the ROC-controlled territories as an integral part of its territory. An exclusive mandate, namely One-China policy, requires that any country wishing to establish a diplomatic relationship with the PRC must first sever any formal relationship with the ROC. According to The Fletcher Forum of World Affairs, "non-recognition of the Taiwanese government is a prerequisite for conducting formal diplomatic relations with the PRC—in effect forcing other governments to choose between Beijing and Taipei." As a result, these countries only allow the ROC to establish representative offices instead of a fully-fledged embassy or consulate for the purpose of conducting practical bilateral relations without granting full diplomatic recognition.
The Canadian Trade Office in Taipei is Canada's representative office in Taiwan, which functions as a de facto embassy in the absence of official diplomatic relations in which Canada recognized the People's Republic of China in October 1970 in accordance with the "one-China policy".

A consulate is the office of a consul. A type of diplomatic mission, it is usually subordinate to the state's main representation in the capital of that foreign country, usually an embassy.

A de facto embassy is an office or organisation that serves de facto as an embassy in the absence of normal or official diplomatic relations among countries, usually to represent nations which lack full diplomatic recognition, regions or dependencies of countries, or territories over which sovereignty is disputed. In some cases, diplomatic immunity and extraterritoriality may be granted.
The Consulate General of Canada in Chicago is a Government of Canada diplomatic mission responsible for Canadian interests in the states of Illinois, Missouri, Wisconsin, northwestern Indiana and the Kansas City metro area. The Consulate General is part of a worldwide network of Canadian diplomatic and trade offices, including more than 15 across the United States. In the Midwest, Canada accounts for more than 35% of the region's international trade. Canada is the largest export market for Illinois, Missouri and Wisconsin, larger than Mexico, China, Brazil, Australia, and Japan combined. The Midwest–Canada trade relationship is worth more than $60 billion annually and supports more than 650,000 Midwest jobs. Canada is also the largest foreign supplier of oil, natural gas, electricity, and uranium to the U.S. The trade partnership, along with an integral energy relationship, a shared responsibility for the Great Lakes and the environment, and the vast cultural, academic and tourism ties between the two countries, are just a few examples of why the Canada–U.S. relationship is so beneficial and meaningful to both nations. The mission's 27 staff members in Chicago work to further this relationship by promoting Canada's interests in this region through stronger trade and economic ties, as well as enhanced political, academic and cultural links between Canada and the Midwest.

Barbados' High Commission remained at that location until the mid 1980s when it moved to its present location at the corner of 1 Great Russell Street in London's Bloomsbury neighbourhood.
