The Czech government office said the document was signed remotely by Czech Prime Minister Andrej Babis and U.S. Secretary of State Mike Pompeo.

The signing comes amid a global battle between the U.S. and China’s Huawei, the world’s biggest maker of network infrastructure equipment. Huawei has become the target of U.S. security concerns because of its ties to the Chinese government.

The declaration says that “protecting communications networks from disruption or manipulation, and ensuring the privacy and individual liberties of the citizens of the United States and the Czech Republic, are vital to ensuring that our people are able to take advantage of the tremendous economic opportunities 5G will enable.”
