You messed the grammar up in the title Yog, you need to change it to something like either:

China makes a breakthrough in domestic MRI technology despite the long-standing foreign blockade

Or to :

China’s domestic MRI technology breaks through the long-standing foreign blockade

Medical breakthroughs in sanctioned socialist countries always brings a tear of joy to my eye

The West blockaded MRI technology to China? WTF does that have to do with national security?
