A series of events is being launched as part of a Government drive to encourage smaller firms to export goods and services.
Thousands of companies will be offered advice this week, especially on how to deal with countries in South East Asia.
UK Trade & Investment (UKTI) said its Export Week will focus on mid-sized businesses.
Trade Minister Lord Livingston said: "There has never been a better time for Britain's businesses to break into new international markets and Export Week will highlight the lucrative opportunities available and how we can help firms take advantage.
"Exports to high-growth markets like China, India and Brazil are at all-time highs and show that the Government's long-term economic plan to create jobs and reduce the deficit is working.
"Exporting helps companies grow and research shows that exporters do better with UKTI's help. I encourage all companies with global ambitions to get in contact with UKTI this week."
The Federation of Small Businesses (FSB) said more smaller firms than ever were looking to export, especially those in manufacturing, research and development and engineering.
Chairman John Allan said: "Small businesses will have a major part to play if the Government is to meet its challenging targets for 100,000 new exporters and to double the value of exports by 2020. Starting to export is a big step for small firms.
"They therefore need tailored advice and support which will allow them to overcome the barriers to exporting that have been repeatedly identified by our surveys.
"There is also a major job to be done to raise awareness of the support UKTI offers small firms thinking of starting the export journey."
