Hmmm... I would say yes, the RC church at this point seems to be making more overtures toward reuniting.
But the RC is much bigger than the OC church and thus appears to have a stronger hand. So it is like asking whether the European Union, which to a significant extent sets members' economic policies, is more open toward uniting with the independently-prosperous country of Norway. Or whether striking sweatshop workers in a third world country are more open to coming to terms with a multinational company. In other words, if one group is making more overtures toward reuniting, it may simply be that thy have a stronger hand.
Another reason may be that the RC church is in the western countries, which in the centuries since the Reformation period have grown to have a less closed religious outlook, which can make them give less importance to religious differences.
But to get back to what I said about a stronger hand- should the OC church at this point reunite with the RC church, it would seem to make the OC church abandon its own beliefs to that of Rome, since the RC church sees the Patriarchs as the Pope's direct subordinates. And it is hard to "agree to disagree" on this matter.
It is like a Christian woman marrying a nonChristian, where one officially says the other must obey him/her in everything, including religion, while the other disagrees on this point. Admittedly in marriage you really don't have to agree about everything.
But in the Church's idea of communion, you are spiritually one church. So you would have a situation where the senior leader officially considers everyone his direct complete subordinates, and the other Patriarchs disagree. But being the senior leader, it still seems his word would carry somewhat more weight than any other leader's. And in reuniting they would be acknowledging his authority, which would suggest also acknowledging the kind of authority he has announced for himself. It would mean organizationally uniting with and recognizing the authority of someone who considers their authority to place you as their complete subordinate. That is why I think the OC church cannot organizationally unite with the RC church and still "agree to disagree" about this.
So to better understand who is really more open to uniting, you may consider who is more open to giving up their position on this point.
Is the Pope really open to giving up his claimed status as complete leader? If not, then strong moves to unity by the RC church would appear to me to be overtures to organizational acquisition by the RC church.
Are the Orthodox open to accepting him as their complete leader? If not, then it appears they are would be going against their beliefs and subordinating themselves.
I mean, if you agree to buy someone's car and you say that as part of the deal you pay only $5,000 and the seller says that you must pay $10,000, then what kind of agreement do you have? If you fool yourselves into thinking you can "agree to disagree" and go ahead with it and never pay the full $10,000, then it is really only the contract you said it was.
Or imagine the US and the British Empire reuniting around the time of WWI, in a situation where the US recognized the stronger, larger British Empire as its "big brother", but the two disagreed over whether the US would be controlled by the British empire or whether they were equals. LOL.
Now, admittedly, uniting the Churches should be a goal, I believe, since they are also other Christians. And this goes beyond buying a car or joining countries together. But considering the organizational inequality, it doesn't seem to make sense, if not logically then at least practically so long as the RC church and OC church disagree over whether the Pope controls the other Patriarchates as his complete subordinates.
