China has raised tariffs on US goods to 125% as the trade war with the US over Donald Trump's global tariffs escalates.
Beijing faces a 145% levy on some of its goods imported to the US.
President Xi Jinping called on the EU to join Beijing in opposing "bullying" from the US, and said "there are no winners in a tariff war".
Despite this, Donald Trump said he is still hoping to secure a deal with Beijing, adding they would "end up working something out that's very good for both countries".
Witkoff,
Trump’s special envoy for the Middle East, is due to take part in
mediated talks with Iranian Foreign Minister Abbas Araghchi in Oman on
Saturday.
The
visit to Russia comes as negotiations on a ceasefire have stalled
following talks in Saudi Arabia last month.
Russia is demanding the
reconnection of one of its largest state banks to the SWIFT
international messaging system that’s under the European Union’s
jurisdiction as a condition for accepting a US-brokered truce in the
Black Sea.
U.S. Special Presidential Envoy Steve Witkoff arrives in Russia — Kremlin spokesman
The Kremlin would provide
information in due course if Russian President Vladimir Putin held a
meeting with Steven Witkoff, Dmitry Peskov said
MOSCOW, April 11.
/TASS/. US Special Presidential Envoy Steve Witkoff has arrived in
Russia, Kremlin Spokesman Dmitry Peskov said.
"Yes, I confirm that he has really arrived," he told reporters.
Peskov added that the Kremlin would provide information in due course
if Russian President Vladimir Putin held a meeting with Witkoff.
According to data from the Flightradar website, a plane carrying the
US envoy landed in the Russian city of St. Petersburg at about 10:00
a.m. Moscow time (7:00 a.m. GMT).
The
Axios news website reported earlier, citing sources, that Witkoff would
make a trip to Russia for a meeting with Putin. The two held a meeting
in Moscow on March 13, 2025.
The researchers examined political rhetoric in 8 million speeches by
members of the US Congress between 1879 and 2022 to see if the focus of
their language was more on data and facts or personal convictions and
subjective interpretations.
The team noticed a significant decline in the use of evidence-based
political rhetoric since the 1970s, with a historic low in the present.
Over the same period, the researchers observed a decline in legislative
productivity, an increase in the political polarization of both
political parties as well as growing economic inequality in the U.S.
US political rhetoric: Analysis of 8 million speeches shows increased reliance on personal beliefs over facts
Discussion of "alternative facts" has gained sad notoriety in US
politics.
Yet the question has been around much longer: How do people
conduct political debates—is the focus more on facts or personal
opinions?
In the journal Nature Human Behaviour, a team of international researchers led by the Cluster of Excellence "The Politics of Inequality" looked into the matter.
Between facts and personal convictions
"In many democracies, there is currently much concern about 'truth
decay': the blurring of the boundary between fact and fiction, not only
fueling polarization but also undermining public trust
in institutions," explains lead author David Garcia, a professor of
social and behavioral data science at the University of Konstanz.
Together with his research colleagues in the UK, Israel, Austria and Germany, Garcia examined the political rhetoric used in congressional speeches over a period of more than 140 years.
Their focus was on the question of how politicians express their
conceptions of truth in their language: are they more likely to use
objective facts or personal convictions?
"Productive democratic discourse balances evidence-based and
intuition-based conceptions of truth," Garcia says.
While evidence-based
discourse provides a foundation for "reasoned" debate, intuition
contributes emotional and experiential dimensions that can be critical
for exploring and resolving societal issues.
However, if facts are given less weight and the balance is off, it
jeopardizes political discourse. This is exactly the development the
researchers have observed in the US' congressional speeches.
Between 1879 and the middle of the 20th century, the ratio of facts
to intuition used in congressional speeches was relatively stable and
balanced.
After 1940, the balance even tipped towards facts and peaked in the
mid-1970s. From 1976 to 2022, however, there was a significant,
continual decline in the use of facts in congressional speeches, with a
historic low in the present.
Both US parties are affected by this downward trend, although the drop has been even steeper for Republicans since 2021.
This negative trend not only applies to congressional speeches: the
results are similar for analyses of Twitter/X posts by members of
Congress from 2011 to 2022, the researchers say.

"One remarkable aspect of our results is the strong association
between evidence-based language and performance," co-author Professor
Stephan Lewandowsky, Chair in Cognitive Psychology at the University of
Bristol, says.
"The more speeches in Congress reflect a reliance on evidence and
facts rather than intuition, the better the performance of Congress and
the less polarization between parties.
Conversely, the increasing reliance on intuition-based language since
the 1970s has been associated with a decline in performance and
increasing polarization. Clearly it matters how politicians use language
in the legislature."
The method behind the study
How can you analyze 8 million congressional speeches? The team led by
David Garcia relied on computational data analysis methods.
"We undertook a massive effort to track long-term trends in how the
language of the U.S. Congress has evolved by analyzing Congressional
records spanning nearly fifteen decades," first author Segun Aroyehun
explains.
"We used advanced text analysis to assess the meaning of words in
speeches and compared them to the meaning of words in dictionaries,
capturing conceptions of truth. This allowed us to observe the focus of
speeches over time."
They started by identifying representative, distinctive keywords
linked to either evidence-based or intuition-based rhetoric. The list
included 49 keywords for fact-based language (e.g. terms such as
"analyze," "data," "findings" and "investigation") and 35 keywords for
intuition-based language (e.g. "point of view," "common sense," "guess"
and "believe").
The team then calculated the ratios of the respective categories of
key words used in 8 million texts. The resulting figure, EMI or
"Evidence-Minus-Intuition," describes the relationship between
evidence-based and intuition-based rhetoric. A positive EMI indicates a
higher proportion of facts, while a negative value indicates a higher
proportion of personal opinions.
The analysis method was developed in a previous project. Jana Lasser,
who has been Professor of Data Analysis at the University of Graz since
2024, examined the linguistic patterns of Twitter posts by members of
the US Congress between 2011 and 2022.
"Even during this period, there was a change in the argumentation
style," explains Lasser. "Personal beliefs gradually gained in
importance and were increasingly presented separately from scientific
facts."
