With wildfire blazing and temperatures hitting record highs in Europe, one China-made product has never been hotter: air-conditioners.

Europeans, who have been slower to adopt AC than those living in other parts of the world, are lining up outside stores and driving long distances in the hopes of securing AC units as blistering summer temperatures in some areas surge past 100 degrees Fahrenheit.

Major Chinese brands Midea, Gree and Haier are reporting AC higher sales overseas, just as leaders in countries such as France, Germany and Belgium are threatening to impose tariffs on Chinese imports, which they say are damaging their own industries.

While air conditioning accounts for a small portion of Chinese exports to the EU, China has seized on the surge in sales as evidence that European consumers need Chinese products.

A column recently published by the official state-run news agency Xinhua criticized European policymakers for ignoring the needs of consumers, titled: “The air conditioner paradox: Europe is too hot for tariffs on China.”

“Blocking Chinese ACs won’t fix Europe’s problems –– it will only make life harder for ordinary people,” the author of the op-ed wrote.

The EU and China will hold discussions over the next few months to address the record trade imbalance of nearly 360 billion euros, or about $406 billion, as of last year. The gap has widened in recent years as China has ramped up exports, particularly of electric and hybrid cars that threaten to displace Europe’s biggest auto brands.

“It makes trade negotiations extremely difficult,” said Cameron Johnson, a supply chain expert and senior partner at Tidalwave Solutions, a Shanghai-based consultancy.

“If you’re a government, you cannot tell people, ‘Sorry, you can’t have air conditioning because we don’t want Chinese overcapacity.’”
