More related to economic thread, but it's likely they will use Chinese tech to build the roads and ports,

Kra Canal is out, to be replaced by roads

From SCMP.com
The canal is the better idea.

They would dig two canals, one for ships going east and one for ships going west. Then they can build a road and rail by the side of it.

Is that article by SCMP or Bloomberg? Either way, sounds like propaganda.

Initial story from twitter,
"Thailand has abandoned considerations of the Kra Canal due to environmental reasons, but still seeks to bypass the Strait of Malacca in shipping with a road-and-rail link between seaports in southern Thailand cutting 2 days of shipping,

This O-Ran is impractical to the point of being silly.

China is building and has built stand alone 5G networks today.

The bureaucrats touting O-Ran should give an indication when a manufacturer will produce such a product for that 5G network.

At this point, we hear radio silence!

:D :oops:
o-ran isn't so easy,
The hole in the Trump administration’s emerging anti-Huawei strategy
Software-based wireless technology can overcome China's edge in 5G hardware, top U.S. officials hope. But the White House may need to nudge the chipmakers first.

Everyone here (hopefully) agrees with you but that does not change the fact that the U.S. is determined to create a coalition of the Five Eyes, the EU, Japan, SK, India & more to impede China and deny it access to technology and capital.

China cannot expect ANY mercy from the world. That is just how it is.

That is why I keep saying China needs to massively increase investment in basic and applied research, cultivate an open culture where independent thinking is welcomed, welcome diversity of highly skilled workers from other countries, and work with other countries (such as Pakistan) where it can to cultivate network effects of scientific collaboration.


it seems you are never tired to preach this “Grand Anti-China Alliance". ask america to form an anti Iran alliance first.

From SCMP.com

"Thailand looks to cut Malacca Strait shipping time by land link between Indian, Pacific Oceans
  • The highway and rail passageway connecting the two oceans would bypass the congested Strait of Malacca off Malaysia and Singapore
  • Thailand says the 100km ‘land bridge’ between two seaports would replace previous plans for a canal, and would cut shipping time by over two days
This canal needs to be guarded against the Indians.

btw, huawei's networks operations/monitoring center (worldwide) is located in India, right? They built it like 5+ or even 10 yrs ago? It's easy to assume both Chinese and Indian engineers/technicians manage the site,, so it would be interesting how both ppl adapt to current political relations.

"If enforced starting in September, the new rules will eventually impede the Shenzhen-based company’s ability to fulfill its obligations with China’s telecom majors in building the country’s next-generation network infrastructure — Huawei already accounts for as much as 60% of mobile network infrastructure. HiSilicon’s Tiangang series of semiconductors — manufactured by TSMC using advanced 7 nm node process technology — are critical to the functioning of Huawei’s 5G base station offerings. The firm appears to have stockpiled some semiconductors, but if production at TSMC is fully cut off, it will not be able to continue producing key pieces of equipment undergirding new infrastructure very far into 2021. New infrastructure is likely to require new approaches at the equipment level, particularly if Huawei rival ZTE cannot ramp up fast enough to take up some of the slack."

a. It specifically said 7nm chip in Huawei 5G base station.
b. Stockpiles will empty out in 2021

However, we all know Huawei has "solutions" which could be any combination of these:
- a semi line in Beijing mentioned by WTAN(?)
- 28nm resolution litho machine from SMEE will do the job even for 7nm node
- another line, perhaps w samsung
- could even be using FPGAs?

The thing is, Huawei/China seem rather calm which could mean they are confident enough of several solutions.

Yes....Huawei is building a 28nm FAB with Localised Equipment which should be ready next year.
I have heard that Huawei is looking into using FPGAs in its 5G Base Stations. These FPGAs can be made using the 28nm process with no problems. A FPGA made by Huawei itself, should be cheaper.

If Huawei wants to use SOCs in its Base Stations it will probably have to redesign to use 14nm Chips. There is currently a Project to develop a fully localised 14nm Chip Manufacturing line which will be ready in 1-2yrs time.

Hopefully Samsung can provide 7nm Chips for Huawei Mobiles and 5g Base stations in the interim.

Huawei will be able to make its own 5/7nm Chips using the SMEE 28nm DUV, as soon as a Localised 7nm Manufacturing Line is developed. The Government should prioritise the development of this localised 7nm Production line as soon as possible.

Hi WTAN,

Question, will SMIC lent its personnel and expertise to Huawei? will it adverse affect SMIC expansion plan and resources? And how about the 45nm fab Huawei had build for this year? is this fab use in producing FPGA? sorry again for being a nuisance.

Thank you, WTAN, for the excellent info and explanation. Huawei then should be able to fill all 5G base station orders:
for China, each year from 2021-25 Huawei must build 500K/year 5G base stations..then also tens/hundreds thousands more per year for other countries.

The Government will certainly get SMIC or Huahong to lend its expertise to Huawei as they are no longer able to do business with Huawei in any case. National Service for SMIC/Huahong. This is probably a one off thing to get Huawei established in the Semiconductor business.

Building the 45nm FAB is probably to get experience in manufacturing semiconductors for Huawei. A learning process. Huawei probably got a 65nm DUV machine from SMEE. Huawei will probably sell these Chips to Industries and manufacturers which still require 45nm Chips.

The FPGA will use the 28nm process. American company Xilinx built its 28nm FPGAs for many years sucessfully.
