China’s water technology sector expands exports to tackle climate challenges
Islamabad, Nov 10,2026: China’s growing expertise in water treatment, desalination and intelligent water management is strengthening its position in international markets, as developing economies increasingly seek advanced technologies to address water scarcity, droughts and climate-related challenges.
Chinese manufacturers are expanding their presence in water-stressed markets across Asia, the Middle East and Africa, supplying filtration equipment, desalination technologies and engineering services that can support long-term water security and climate adaptation.
According to UN Comtrade data, China’s exports of water-filtering and purifying machinery reached approximately $2.05 billion in 2025, representing an increase of around 28% compared with 2020.
The United States, Indonesia, Vietnam, Malaysia and Russia were among the major destinations for these exports, reflecting the market reach of Chinese water technologies across developed and emerging economies.
Chinese companies are also expanding their involvement in water infrastructure projects in Saudi Arabia, the United Arab Emirates, Egypt and several African countries, creating opportunities for international cooperation in water treatment, desalination and infrastructure development.
The expansion of China’s water technology industry is supported by substantial domestic investment in water security and modern infrastructure.
According to China’s Ministry of Water Resources, the country invested more than 1.28 trillion yuan in water conservancy projects during 2025, undertaking 47,563 projects nationwide.
Official figures released in January 2026 showed that cumulative investment in water conservancy reached 5.68 trillion yuan during 2021–2025, reflecting China’s emphasis on flood protection, irrigation, water conservation and modern water infrastructure.
Ahtisham Iqbal, Senior Scientific Officer at the Pakistan Agricultural Research Council (PARC), told Wealth Pakistan that China’s growing capabilities in water technologies could provide developing economies with practical solutions to increasing pressure on freshwater resources.
“For countries facing recurrent droughts, glacier loss and more erratic rainfall, the central issue is no longer only how to conserve existing freshwater. Governments also have to expand the usable water base through desalination, wastewater recycling, leakage reduction and advanced treatment systems,” he said.
Iqbal explained that many developing countries had traditionally focused on dams, reservoirs and groundwater extraction, while investment in water reuse and treatment infrastructure remained relatively limited.
He said China’s expanding water technology industry could help countries adopt more diversified approaches to water security by combining conventional infrastructure with modern treatment, recycling and monitoring systems.
“Pakistan’s priority should be to match technologies with specific geographic and economic needs rather than adopt them uniformly. Coastal cities such as Karachi and Gwadar face different water-security challenges from inland agricultural regions,” he said.
He added that desalination could be more relevant to coastal urban and industrial water supplies, while wastewater reuse, aquifer management and efficient irrigation systems would remain critical for agricultural areas.
According to Iqbal, cooperation with China could also help Pakistan strengthen groundwater monitoring, improve industrial wastewater treatment and introduce more efficient water-management practices.
Dr Saima Ashraf, Assistant Director at the Pakistan Council of Research in Water Resources (PCRWR), said growing international demand for Chinese water technologies reflected a broader shift towards infrastructure capable of addressing long-term climate risks.
“Climate adaptation should not remain confined to emergency responses after floods and droughts. Countries need infrastructure capable of functioning under increasingly unpredictable environmental conditions. Chinese expertise in membrane technology, smart monitoring and water reuse could support this transition, particularly where financing constraints have delayed investment,” she said.
Ashraf emphasised that Pakistan should pursue technology transfer, joint ventures and domestic technical capacity development alongside the acquisition of advanced water-treatment equipment.
She said cooperation with Chinese technology providers could help establish locally operated systems and strengthen the technical expertise needed to maintain water infrastructure over the long term.
“For Pakistan, the priority should be to develop local technical capacity through pilot projects in industrial estates, water-stressed urban centres and coastal areas. Successful cooperation would be measured not merely by installed treatment capacity but by reduced freshwater consumption, lower operating costs and the ability of local institutions to maintain these systems independently,” she explained.
She added that industrial partnerships could also support employment generation and help Pakistani businesses develop expertise in water treatment, equipment maintenance and related engineering services.
“Pakistan’s future cooperation with China should increasingly focus on developing domestic capabilities rather than merely acquiring imported machinery. Joint ventures, technology transfer and locally operated treatment facilities could help industries reduce freshwater consumption while creating technical expertise and employment opportunities,” she said.
Ashraf, however, pointed out that desalination and advanced water-treatment systems required reliable energy supplies, regular maintenance and sustainable financing. She stressed the importance of local feasibility assessments before adopting such technologies on a large scale.
As water scarcity becomes an increasingly significant economic and environmental challenge, China’s expanding capabilities in water treatment, desalination and intelligent management could strengthen its role in international climate-adaptation cooperation.
For developing economies, including Pakistan, these technologies offer opportunities to improve water security, strengthen industrial efficiency and build domestic technical capacity through sustained partnerships with Chinese companies.
