President Trump's former chief economic adviser Gary Cohn said on CBS's "Face the Nation" Sunday that he thinks the president's tariffs on China "totally" hurt the United States, and that he doesn't believe they have helped achieve a different "outcome" with China.

The newly inked "phase one" U.S.-China trade deal calls for China to boost purchases of U.S. energy products — including crude oil and liquified natural gas (LNG) — by $52.4 billion over the next two years.

Why it matters: China is the world's largest oil importer and second-largest LNG consumer.

There was limited fanfare from the stock market after President Trump and Chinese Vice Premier Liu He signed the "phase one" trade deal yesterday.

What happened: The 94-page document will roll back some U.S. tariffs on Chinese goods and see China increase purchases of U.S. goods and services by $200 billion over two years, but it leaves more questions than answers, experts say.

President Trump and Chinese Vice Premier Liu He signed Wednesday the "phase one" trade deal between the U.S. and China.

The big picture: The 18-month trade war between the two countries has largely lacked significant breakthroughs, causing major market uncertainty and hammering the U.S. manufacturing industry. This reprieve — which will take effect in 30 days — could help that sector to rebound this year.

President Trump has shrunk America's global presence in many ways, but he has also at times placed high-risk bets on its superpower status.

Driving the news: Trump didn't want war with Iran, yet he ordered the killing of Iran's top commander. That requires enormous faith in the shield of American military superiority.

The wine industry descended on Capitol Hill this week in a last-ditch attempt to avert 100% tariffs on all EU wines — as well as cheeses, cosmetics and other consumer products.

Why it matters: The U.S. has declared its intention to impose these tariffs as retaliation against the way that European nations illegally subsidized Airbus. But if they go into effect, the brunt of the pain will be borne not by European companies, but by Americans.

The World Bank cut its global growth forecast for the fourth straight time on Wednesday, reducing expectations by 0.2 percentage points each year for 2019, 2020 and 2021.

"Global economic growth is forecast to edge up to 2.5% in 2020 as investment and trade gradually recover from last year’s significant weakness but downward risks persist. ... U.S. growth is forecast to slow to 1.8% this year, reflecting the negative impact of earlier tariff increases and elevated uncertainty."

Even after a very tough year in which farm debt has risen, sales have declined and the prices of key exports like soybeans have plummeted, large-scale U.S. farmers remain upbeat on their prospects, a survey shows.

Driving the news: The latest results of the Purdue University and CME Group reading of the agriculture economy showed a slight decline in December, but that was down from an all-time high touched in November.

U.S. farmers have been given a bit of a lifeline by the "phase one" U.S.-China trade deal, but without concrete specifics on what China will purchase there remains some worry about how they will be able to support themselves and their farms in 2020.

Background: Farmers had a rough 2019, even with a hefty subsidy package provided to them by the Trump administration as relief from the trade war.

The Federal Reserve has released a study that found the tariffs imposed by the Trump administration in 2018 led to higher prices and fewer manufacturing jobs.

The big picture: President Trump has ordered tariffs on a number of countries and a range of goods in a bid to protect manufacturers and correct what he sees as "unfair" trading practices — most notably in the United States' relationship with China.
