The United Kingdom comprises of England, Scotland, Wales, and Northern Ireland.  These nations have their own identity and culture.
The terms ‘English’ and ‘British’ are different.  The ‘British’ denotes a native of England, Scotland, Wales or Northern Ireland. ‘English’ refers to some one from England. In the same way you can distinguish ‘Scots’ ‘Welsh’ ‘Irish’. Apart from people of these four courtiers, UK has large populations not only from Asia but also from courtiers like Australia, New Zealand, South Africa, Canada etc. Naturally there is a mixture of all these culture in UK.
“The British have strong emotions though they do not display it in public. They are very much reserved.   They do not want their privacy to be disturbed. They will never interfere in others’ affairs also.
They are generally reserved, and at the outset they may not seem to be friendly. Friendships take quite sometime to build; but once built it may be deep and everlasting.
As already mentioned UK comprise people from a large number of countries. As a result there is an interesting mix of culture and communication styles.  The British are direct and unassuming while communicating with people they consider equal to themselves. The may be quite casual while communicating with someone they know well although they will still be reserved. Official written correspondence is strictly as per protocol.
The British business gives value to punctuality. Coming late will never be tolerated. In general, meetings will be rather formal. In the meetings, the senior most person will be leading the discussions. Meetings always have a clearly defined purpose.

Intercultural communications field has become prominent in all sorts of spheres, may it be trade, commerce politics, education and what not. a cultural difference  will  have undesirable  effect on the prospects of business.
The clash is there both in international level and national level. No doubt it brings about challenges.
The objective of Intercultural communication training is to reduce the harmful effect the culture can have on the day to day business. Every culture has its own norms, manners, values etc which may not be acceptable to other cultures. Consequently there is bound to be misunderstanding. The training should nullify this to a great extend, which will ultimately have a bearing on the business development.
Let us look at UK business culture. The British are well known for punctuality. They are very particular about time management. For them time is precious. The same may not be the case with people of many other countries.
The British give importance to humor while they talk. They presume that this will take them closer to people. A Japanese colleague may not be able to digest this initially.
Inspiration, suggestions, criticism, etc. are all part of a British corporate meeting. This may not be the case in certain other countries. So when a person of that culture visits UK, he may be a fish out of water. There is going to be cultural imbalance and misunderstandings in both directions.
Intercultural communication training helps the entrants to become familiar with the new culture. The training should bring him closer to the new environment and he should have no more problems in adjusting. In short, the training should put an end to the brunt of cultural differences.
