Pakistan and the United Arab Emirates maintain strong economic relations with each other, with the UAE being the second biggest trading partner of Pakistan in terms of bilateral trade.[14] A large skilled and semi-skilled Pakistani workforce contributes to the UAE economy. Around 20% of Pakistanis are white-collar professions, and the remaining 80% are involved in the blue-collar industry.[15] The ratio of blue-collar Pakistani labour migrating to the UAE has dropped since 2008, although the volume of remittances has increased.[16] Pakistan ranks among the top five sources of migrant professionals in the UAE.[17] The United Arab Emirates is a major investment destination for Pakistan. Pakistanis are among the top ten investors in the UAE property market, ranking as the second largest nationality that bought most property in Dubai.[18] Many wealthy Pakistanis have bought expensive properties in Dubai and have second homes there.[19][20] Pakistani expatriates in the UAE are actively involved in the country's business, investment and services sectors.
