Copenhagen and Beijing will seek to work together on water technology so that to better protect and manage the drinking water resources, said Copenhagen Mayor Frank Jensen.

Jensen has left for Beijing on Wednesday with a Danish business delegation.

During his visit, Jensen will meet with Beijing Mayor Wang Anshun and the two sides will sign a memorandum of understanding (MoU) on drinking water management, the mayor told Xinhua in an interview prior to his departure.

Jensen, who visited China two years ago, said he was now traveling to Beijing again to strengthen the business relations between the two cities, because both cities have a strong value when it comes to sustainable urban development and green growth.

"Clean water, especially clean drinking water, is very important for big cities like Beijing," Jensen said, adding Copenhagen has a lot of experience in reducing the loss of water in its pipes.

According to the mayor, the loss of drinking water in the pipes of Copenhagen is only 7 percent, Jensen said.

Included in the delegation are representatives from around 20 Danish companies, including Danfoss, Grundfos, Rockwool, COWI and Ramboll.

Jensen said the Danish clean-tech companies will be able to meet with Chinese officials during their four-day visit to discuss ways to bring Danish clean-water and district-heating technologies as well as urban-development consultancy to the Chinese market.

"By drawing on my working relationship with the Chinese authorities, we hope to utilize Copenhagen's reputation for sustainability and be able to do more business with China and to create more jobs in Copenhagen and Denmark," he added.

Beijing and Copenhagen have become "sister cities" since 2012, and the two capital cities have already signed agreements to collaborate in areas such as sustainable urban development and tourism.

Jensen said he hoped the visit would further strengthen the partnership between the two cities.

During his visit, Jensen will also work to promote Danish district-heating technology and promote the Danish capital as a destination for Chinese travelers.

By 2020, exports of district-heating technology to China are expected to triple to 215 million euros(265 millio US dollars), Jensen said.

The number of Chinese visitors to Copenhagen has risen by 70 percent since 2010. (1 euro = 1.25 US dollars)
