Trade War Weekly Roundup: Outbound Investment, China Curbs

This trade war weekly roundup covers the six Trade War daily reports Peter’s World published from Oct. 18 to Oct. 25, 2026. No Trade War edition ran on Oct. 21 or Oct. 22. The roundup gathers the week’s main threads, then adds our analysis. Each fact appears once, with its source, and the full daily list is at the end.

The week in brief

Washington and Beijing: investment, technology and export controls

The Treasury Department proposed rules to carry out the outbound investment law, covering US deals in six technology areas, including semiconductors and biotechnology. China’s Foreign Ministry said it would “take necessary measures” in response, and its commerce ministry formally opposed the rule and reserved the right to take countermeasures, The Straits Times reported.

Earlier in the week the State Department sanctioned five Chinese entities linked to a former Google engineer’s theft of trade secrets, including the startup investor MiraclePlus. The Department of Homeland Security ordered DeepSeek products removed from federal civilian systems, according to the Federal Register. China told Washington to stop “discriminatory measures” against Chinese research institutions after a lawmaker sought to list 58 more schools and 62 labs.

Beijing also tightened its own controls. China’s Ministry of Commerce and customs agency said tunnel boring machines, some excavators and long-range drones will need export licenses from Nov. 18. China’s statistics bureau said exports grew 16.4% in the first nine months of 2026 while fixed-asset investment fell 7.2%.

The US Trade Representative proposed extending the pause on fees for Chinese-linked ships at US ports to Jan. 9, 2027, with comments due Oct. 30, according to the Federal Register notice.

North America: Canada and Mexico

The White House changed which Canadian goods face its 50% tariff, removing plywood and some paper products from Oct. 30, according to a White House fact sheet. The Commerce Department set final duty rates on Canadian softwood lumber, with most exporters facing a 10.64% antidumping rate plus a 14.11% subsidy rate. Mexico’s economy secretary, Marcelo Ebrard, reported progress in Washington on cutting US tariffs on vehicles, steel and aluminum, and President Trump said a deal was close, EFE reported.

Deals in Asia and Latin America

Secretary of State Marco Rubio told Central Asian ministers that US commercial deals with the region have passed $25 billion since November 2025. Uzbekistan’s president said talks with American investors in Samarkand produced 54 agreements worth about $12 billion. Rubio also said a trade deal with India is “very close”, The Economic Times reported. Paraguay became the 26th signatory of Pax Silica, the State Department’s supply-chain declaration, and offered minerals and hydropower.

Other governments signed their own deals. Vietnam signed a free trade agreement with the European Free Trade Association (Switzerland, Norway, Iceland and Liechtenstein). The European Union signed a raw-materials partnership with New Caledonia, a major nickel producer.

Energy and Russia

Brent crude settled at $116.72 a barrel on Oct. 23, its highest close since April 29, Reuters reported via Euronext. The Energy Department approved a Strategic Petroleum Reserve exchange of up to 400,000 barrels for a Louisiana refinery. The first Russian diesel tanker under the US deal loaded 40,000 metric tons and is due in New York on Nov. 7, The Kyiv Independent reported. Our Russia-Ukraine coverage tracks the EU’s sanctions response.

What changed this week

Analysis (Peter’s World’s view): The US-China contest moved from tariffs to capital and technology. Treasury’s investment rule, the DeepSeek removal order and the MiraclePlus sanctions all target who can fund, build or use Chinese technology, not the price of goods at the border. Beijing answered in kind with export licenses on heavy machinery and drones. At the same time, Washington eased some pressure where it hurt US buyers: it trimmed the Canada tariff list and proposed keeping the China port fees on hold.

Why it matters

Analysis (Peter’s World’s view): Investment and technology rules are harder to reverse than tariffs, because they reshape company plans for years. Chinese officials have now promised countermeasures twice in one week, so US firms with China exposure face a real risk of retaliation. Oil near $117 also raises the cost of every trade fight. In that setting, new minerals and market deals with Central Asia, India and Paraguay matter as much as the tariff rate on any single product.

What to watch next week

Oct. 30: Comments close on the USTR port-fee pause, and the revised Canada tariff list takes effect.
Whether China names specific countermeasures against the Treasury investment rule.
Any signed text for the US-India and US-Mexico deals.
Nov. 7: The first Russian diesel cargo’s arrival in New York.
