Modern diplomatic methods, practices and principles have largely come from European customs since the 17th century. At the beginning of the 20th century, diplomacy became increasingly professionalized; The 1961 Vienna Convention on Diplomatic Relations, ratified by most of the world`s sovereign states, provides a framework for diplomatic procedures, methods and behaviour. Most diplomacy is conducted by accredited career diplomats through a separate political institution (for example). B a ministry or department of foreign affairs), usually with the support of staff and diplomatic infrastructure, such as consulates and embassies. Diplomacy is also carried out through other offices such as envoys and ambassadors. The term diplomat is therefore sometimes generally applied to diplomatic and consular staff and officials of the Ministry of Foreign Affairs in general. [3] Minister, Minister-Adviser Apart from his account of a cabinet-officer (i.e. “Minister of Foreign Affairs”), a minister was traditionally a head of the diplomatic mission, directing a message rather than a message. Since there are few messengers left, the title is increasingly used to refer to the secondary officer of a great message. It has therefore become increasingly important to think of the senior advisor under the ambassador. To avoid confusion with the old connotation, the United States and a number of governments refer to these high-ranking deputy heads of mission as high-ranking “ministerial advisors.” In this procedure, the State of origin formally requests the approval of the receiving state by the host state before proceeding with the establishment of a diplomat in the host state. If the designated diplomat is acceptable to the receiving state, the host state gives approval.
The arriving diplomat carries a letter of accreditation, normally called a letter of credibility or “letter of credence,” from the sending state to the head of state of the host state when he arrives in the host state. This is submitted to the host head of state and the diplomat is thus accepted as a member of the diplomatic corps of the host state and placed on a diplomatic list. The designated person enjoys diplomatic immunity in the host state. Delegation once again engaged in two directions within the framework of diplomacy. “delegation” may be the term used to refer to the specific powers conferred by his government on a diplomat acting in certain circumstances. It also refers to an official party sent to an international conference or other special diplomatic mission. Long before the Tang and Song Dynasty, the Chinese had sent emissaries to Central Asia, India and Persia, beginning with Zhang Qian in the 2nd century BC. Another notable event of Chinese diplomacy was Zhou Daguan`s mission to China in the Khmer Empire of Cambodia in the 13th century. Chinese diplomacy was a necessity in the particular period of Chinese exploration. Since the Tang Dynasty (618-907 AD), the Chinese have also invested heavily in sending diplomatic envoys abroad for broadcasts in the Indian Ocean, India, Persia, Arabia, East Africa and Egypt.
Chinese shipping was greatly increased during the song Dynasty trading period, with new nautical technologies, many more private ship owners and an increasing number of economic investors in overseas companies.
