Well looks like Scholtz Beijing trip didn't went so well?

Likely ARM like other phytium processors. The current Phytium D2000 seem almosts comparable to (my) 5 year old i3 if based on some geekbench scores in multicore performance. However each single core is considerable lower, so its achieving performance via higher core count which I don't know how that ultimately would affect a typical desktop user.

A 9k wafers per month factory with 8" wafers and 350nm process. This is what passes for strategic in Europe nowadays. This is a close to 3 decades old process. It is only relevant for a company like Silex which makes MEMS devices. This German factory would likely be converted to produce radars for autonomous cars and the like. Without investors it will likely just fail.
If you want to read more scare mongering the article below talks about the Chinese investor in Silex.
RF 5G chips mass production has begun ..
Realize mass production! Domestic 5G radio frequency transceiver chip, "popular" is here
Since the official commercial use of 5G in 2019, 5G macro base stations have basically achieved large-scale outdoor signal coverage. At the same time, the demand for indoor signal coverage is also increasing. As a solution for indoor coverage or deep coverage, 5G small cells play an indispensable role. However, as an important part of small base stations, radio frequency chips are almost monopolized by foreign companies. In the mass production process of localized small base station RF chips, they face dual challenges from the software and hardware levels.
After years of sharpening the sword, the sword has finally become a sharp edge. After continuous investment and painstaking research and development, Dixin Technology has continuously overcome the technical problems of the transceiver chip of the RRU module in the deployment of 5G small base stations in the directions of heat consumption, inefficiency, frequency band conflict, etc., to achieve high-efficiency RF transceiver, High-efficiency power amplification, low-consumption RF transmission and other technical effects, and through a series of rigorous testing and specification approval, the successful mass production of popular series (GC080X) products, which can be widely used in almost all modern digital wireless communication systems, such as general software radio systems, 5G/4G LTE and private network wireless communication base stations, multi-functional intelligent terminals, point-to-point communication systems, etc. Fengxing series products can support the frequency range of 30MHz ~ 6GHz, support ultra-wide and ultra-narrow bandwidth requirements, have dozens of Chinese and international cutting-edge patented technologies, and complete intellectual property layout
Taking Fengxing GC0802 as an example, the frequency range that this product can support is 200MHz ~ 5GHz, which supports ultra-wide and ultra-narrow bandwidth requirements, and the configurable radio frequency bandwidth can support the range of 12KHz to 100MHz. At the same time, the device integrates 12-bit analog-to-digital converter ADC and 12-bit digital-to-analog converter DAC, built-in programmable analog filter, supports analog low-pass filter with minimum bandwidth of 0.7MHz and analog low-pass filter with maximum TX bandwidth of 50MHz Adapter, RX maximum 50MHz analog low-pass filter. The mixer and phase-locked loop are also integrated inside the chip, and the transmitting part is integrated with a driver-level amplifier, which can output a single-tone signal above 8dBm.
The popular GC0802 adopts the industry's mainstream 10mm×10mm, 144-pin chip-scale ball grid array package (CSP_BGA), the chip register read and write control adopts the standard four-wire SPI, the analog RF power supply mainly adopts 1.3V, and the digital part interface power supply adopts 3.3V V or 2.5V. The product has rich development tools and strong technical support. Based on a general performance evaluation platform, the actual measurement results of Loopback: the loopback EVM is 1.4%; the power consumption is 500mW per channel.
Fengxing GC0802 SDR RF transceiver adopts direct frequency conversion architecture, which has excellent performance of ultra-low power consumption, high modulation accuracy and low noise. This product is a highly integrated 2T2R transceiver with functions such as image rejection calibration, local oscillator leakage calibration, transmit power monitoring, spurious rejection, and receive channel gain calibration. It supports TDD and FDD, and supports MIMO and other multi-chip usage scenarios. It is used in traditional base stations, microwave relays, micro base stations, aerospace, satellite, radar, unmanned driving and other application scenarios.

If China is serious about responding, they need not remove nor replace them - just seize and steal them wholesale. Should Americans want to go down the national security path, China is more than well equipped to deal with that. Any company that follows sanctions not approved by a mainland court can be considered an US government actor, and if they don't have the appropriate permits to operate in China as official American representatives, their products, monetary assets, factories and IP can be seized by the state.
For now China is just focusing on keeping their companies innovative and independent by not stifling them with heavy handed government interference, but if they get more pressed in the future, there are many options to go force to force with US.

It says the value of the deficit widened due to the rise in prices, but quantity was reduced.
Well it is out of Scholtz's control. Half of Germany listen to the Anglos.
May I ask, can china produce ArF photoresist domestically?
