This artificial island, built by China, is 2.5 km from Kinmen, Taiwan. CCP has built a huge airport on it.

The world must wake up.

Salutary experience to see this up close today, on the first ever political delegation permitted on a patrol. Thank you @MOFA_Taiwan @TAIWANoac

By engineering isotropic interband coupling in a bilayer photonic crystal, researchers numerically demonstrate a topologically protected, continuous ring of unidirectional guided resonances that locks vortex laser emission into a single direction.

China has built a near-constant naval presence on all sides of Taiwan. See how Beijing is tightening the noose on the island it claims as its own. https://t.co/aLKTlefK8T via @WSJ

CCP spies sentenced in London today but still the regime is omitted from the enhanced tier of the foreign influence registration scheme.

Money talks as trade deals take precedence over national security.

The Committee for Freedom in Hong Kong @thecfhk reports on the Old Bailey sentencing of the two men linked to Hong Kong’s trade office in London for spying on pro-democracy activists on behalf of the Chinese Communist Party (CCP).

Bill Yuen, the former administrative manager of the Hong Kong Economic and Trade Office (HKETO), was sentenced to eight years for assisting a foreign intelligence service. Prosecutors said Yuen used HKETO resources to fund surveillance and intimidation operations targeting Hong Kong and Chinese dissidents in the United Kingdom, before passing intelligence back to officials in Hong Kong.
His accomplice, former U.K. Border Force officer Peter Wai, was sentenced to 10 years for the same offense and misconduct in public office after abusing Home Office databases to obtain information on targets.  

Committee for Freedom in Hong Kong FoundationPublic Affairs and Advocacy Manager Chloe Cheung, @Chloe_chc_25 who carries a HK$1 million cash bountyimposed by the Hong Kong government for her arrest, said:
“Bill Yuen and Peter Wai have rightly been punished today — but let’s not miss the bigger picture. These two individuals are just the tip of a very long spear being wielded by the Chinese Communist Party.
“Hong Kong police issued cash bounties on Hong Kong activists living here in Britain and then used HKETO staff and offices to hunt us down and frighten us into silence. Their vile tactics won’t succeed, but we need more support from the British government to hold those behind the scenes accountable. 
“There have been zero diplomatic consequences for the officials responsible in Hong Kong and China — no sanctions, no expulsions, and — crucially — a greenlight for the HKETO in London, which happens to be in Prime Minister Keir Starmer’s constituency, to carry on with business as usual.
“That’s just not good enough. That’s why we’re building cross-party support to examine the legal basis of the HKETO’s privileges and to repeal the Hong Kong Economic and Trade Office Act 1996.”

❗️BREAKING: sentences handed down in 🇨🇳 interference (HKETO) case:

Bill Yuen 8 years and Peter Wai 10 years in jail (Wai’s sentence includes misconduct in public office).

Almost in tears with relief, on behalf of so many who live under threat of intimidation from Beijing. This is a landmark moment for the UK. For years, dissidents and experts have warned that Beijing’s interference operations are running amok in Britain. Today, the courts have drawn a hard line: run hostile intelligence operations against people on British soil, you’re not going home to a heroic welcome, you're going to a UK prison cell.

The Chinese have a saying 不作不死 (no doing, no dying). In crude English: FAFO. Beyond happy that this is the future Beijing’s proxies can look forward to if they behave in this way, thanks to the National Security Act.

I've come across posts like this many, many times – praising China's safety while denouncing democracies that spend too much time debating "freedoms."

I get it. I don't want to live somewhere I have to watch my surroundings constantly.

But safety isn't the price you pay for freedom. Taiwan, Japan, and Korea are among the safest places. You can walk the streets at 2 a.m without a second thought, and none of them required a surveillance state to get there. Culture, state capacity, and enforcement all shape this, no single model owns it.

China's version comes down to a tyrannical policing and surveillance apparatus that makes the personal cost of committing even petty crime extraordinarily high. But that same apparatus is also the one that disappears the lawyer, the journalist, the dissident.

Europe may have a problem, but China is not the answer to it. Hinting that the problem is having too much “freedom debate” is such a bad take.

Well, well.

Reminder that the decision to approve the 🇨🇳 mega embassy is being challenged in the courts. Full hearing mid-July.
