Beijing appears to be moving toward a model in which religion can exist, but only within clearly defined political boundaries.
The state does not necessarily need to eliminate religion.
It can instead regulate it.
It can determine which organizations are legitimate.
It can supervise religious leaders.
It can regulate religious education.
It can control the construction and appearance of religious buildings.
It can limit foreign religious influence.
And it can promote an understanding of religion that emphasizes loyalty to the Chinese state and national identity.
This model is different from outright religious prohibition.
It is also different from liberal religious freedom.
It is a model of state-managed religion.
For Muslims, that model presents particularly difficult challenges because Islam is both a religion and, for many communities, an important component of ethnic and cultural identity.
The Hui and Uyghur experiences demonstrate this in different ways.
For Uyghurs, restrictions on religion have occurred alongside severe restrictions on language, culture, education, family life and political expression.
For Hui communities, the process has generally been less extreme, but mosque consolidation and architectural changes suggest that the boundaries of acceptable Islamic identity are also narrowing.
The disappearance of domes and minarets therefore carries symbolic importance.
A government does not have to destroy every mosque to reshape religious culture.
It can change what a mosque looks like.
It can determine where mosques are built.
It can decide how many exist.
It can regulate who is allowed to attend.
It can determine what religious education is permitted.
And it can place religious institutions within a political structure controlled by the state.
Over time, those decisions can change an entire community.
That is why the Financial Times investigation into China's mosques was so significant.
Its satellite analysis suggested that thousands of mosques had been altered or destroyed, with the changes extending across regions well beyond Xinjiang.
The scale matters
This is not simply one controversial renovation.
It is a pattern.
And the pattern has a direction.
Toward fewer independent-looking Islamic institutions.
Toward more standardized architecture.
Toward greater state supervision.
Toward a religious identity that is explicitly framed as Chinese.
The government argues that this is a form of cultural adaptation.
Critics argue that it is assimilation.
The difference depends partly on how one defines religious freedom.
If religious freedom means merely the ability to pray inside an approved building, China's system may appear relatively permissive compared with a total ban.
If religious freedom includes the right to organize independently, preserve religious architecture, educate children according to one's faith, maintain cultural traditions and participate in religious life without political interference, the picture looks very different.
International observers have consistently raised concerns about the latter.
Pew Research Center has classified China among the world's most restrictive governments on religion.
The U.S. Commission on International Religious Freedom has likewise criticized the Sinicization campaign as a mechanism for ideological control.
At the same time, China's government rejects many of these accusations.
Beijing argues that foreign governments and human rights organizations misunderstand China's approach and interfere in its domestic affairs.
Chinese officials maintain that religious freedom exists within the framework of Chinese law and that measures in regions such as Xinjiang are necessary to combat terrorism and extremism.
That disagreement is unlikely to be resolved simply through competing statements.
The physical transformation of mosques provides more tangible evidence.
Satellite images do not tell us everything about religious life.
But they can show whether a dome still exists.
They can show whether a minaret has been demolished.
They can show whether a mosque remains intact.
They can show whether a religious complex has been replaced or substantially altered.
And when those changes occur across hundreds or thousands of sites, they become difficult to dismiss as isolated incidents.
There is also a generational dimension.
