So it is certain that, due to sharing a land border with each other, Ireland has a deep connection with the UK in relation to trade, supply, language, to migration and culture. Ireland exports billions of goods and services from the UK. According to a survey conducted in 2013, Ireland exported goods worth €14.8 billion and services worth €5.8 billion to the UK. This equates to almost around 12% of GDP, which is relatively higher than that of any other Member State. Likewise, Ireland's relationship with the United Kingdom is deep and much expanded. According to a survey conducted in 2013, Irish companies invested over €13 billion in the UK with profits exceeding €800 million, equivalent to almost 0.5% of GDP. However, Ireland has a small investment compared to the UK. The UK invested around €51.2 billion in 2013, or almost 30% of Ireland's GDP. Likewise, the financial ties between these two countries are powerful. Several international banks operating in Dublin are closely integrated with each other. Furthermore, many private equity funds operate in and out of Dublin and have a close relationship with the UK which will be forced to dismantle its operations from London due to Brexit. Therefore the United Kingdom and Ireland are instinctive collaborators with each other
