The US and EU officially pledged in Brussels on Tuesday “to promote innovation and leadership by US and European firms”, but America fears this may not include its biggest tech companies: Alphabet, Amazon, Apple, Facebook and Microsoft.

The US, in fact, warned the EU against pursuing “protectionist” technology policies that exclusively target American companies, ahead of Joe Biden’s first presidential visit to Brussels, according to this FT scoop.

The National Security Council wrote last week to complain about the tone of recent comments about the EU’s Digital Markets Act — the draft legislation that aims to curb the power of Big Tech. “We are particularly concerned about recent comments by the European Parliament rapporteur for the Digital Markets Act, Andreas Schwab, who suggested the DMA should unquestionably target only the five biggest US firms,” the NSC said.

It may have been reassured by today’s agreement “to establish an EU-US Joint Technology Competition Policy Dialogue that would focus on approaches to competition policy and enforcement, and increased co-operation in the tech sector”.

Also, in a move seen as countering China’s tech advances, today’s Brussels meeting set up a high-level EU-US Trade and Technology Council, with goals that included “to avoid new unnecessary technical barriers to trade . . . to facilitate regulatory policy and enforcement co-operation and, where possible, convergence”.

Initially, working groups will focus on tech standards for AI and the Internet of Things, and on strengthening supply chains. “Notably, we commit to building an EU-US partnership on the rebalancing of global supply chains in semiconductors with a view to enhancing EU and US respective security of supply as well as capacity to design and produce the most powerful and resource-efficient semiconductors,” said their joint statement.

It appears the Biden administration will fight for the Big Five to be fairly treated in Europe, while giving them a hard time at home. Today, the Senate confirmed the White House’s nominee Lina Khan — an outspoken critic of Amazon — as the Federal Trade Commission’s newest member. Lex says she may shape a new era of antitrust policy, although the break-up of tech companies is not inevitable.
