This was not an everyday standard sequence where most partnership have clear agreements what subsequent bids would show.
Say partner bids 3♥, because he wants to make a nice forcing, much lower level bid over 3♦.
You find your next bid, say 4♦ and partner now bids 6♣, because he can not find another clearly forcing bid.
What will the partnership have gained in this case?

Partner now knows you are 5 - 6 in the minors. Before he knew you were 4-5. If you had bid 4♣, presumably he could now rkcb for ♣
Back to the actual bidding. It seems likely that partner wanted to bid RKCB for clubs because he is missing the KQ. It seems like Easts bid has made it impossible to set the suit as clubs and force. Unless you have an agreement that an immediate 4♥ is rkcb in ♣ I see no solution except the random 3♥ force. I expect partner has Axxxx, KQxx(x),(x) , Axx and it seems like I want to be in 7♣, partner may even convert to 7N with the right hand
