No, at 3:50 in TFA the bill defines holding as: i. an equity interest, ii. a stock, iii. a security, iv. a share, v. a partnership interest, vi. an interest in an LLC, vii. a membership interest, or vii. ANY participation, right, or other equivilent, however designated and of ANY character (emphasis mine).

That's a lot more broad than "Chinese controlling interest".

Edit: and "controlling interest" as defined in the bill means "a holding with the power, whether direct or indirect and whether exercised or not exercised, to determine, direct, or decide important matters affecting an entity." which is much more broad than the commonly understood 51% equity stake.
