The United States and Poland may sign an agreement on 5G wireless network security during Vice President Pence’s visit to Poland this weekend, officials told reporters Friday.

A senior administration official told reporters ahead of Pence's trip to Poland that there could be an announcement "in the next day or two involving a secure 5G network."

The official added that "important steps are being taken, some of which we may be able to announce in the next day or two, to develop a common approach to a 5G network security between our two countries to ensure a secure and vibrant 5G ecosystem."
