Narrative:

We were tracking out td 104 degree radial and needed to be at FL330 before we could go direct to elato. The controller turned us to 020 degrees and we used only 10 degree angle of bank to preserve our climb performance. Then as we were passing FL310 he cleared us direct elato. We were in a slight right turn to avoid a build-up. I elected to go around the build-up prior to going direct elato. Then he started yelling at us that we were going out of his airspace into taipei's airspace. We then went direct elato. 1) our climb performance put us right on the level at elato regiment. 2) our 10 degree bank turn to keep our climb performance wasn't enough turn to keep us out of taipei's airspace but I wanted to keep up our climb performance. 3) so we put ourselves at risk. But I felt he wanted us level at FL330 and that is what I was trying to accomplish.

Title: SLOW CLBING ACFT HAS TROUBLE TRYING TO MAKE XING RESTR. IT ALSO FLIES INTO FOREIGN AIRSPACE UNAUTH BY ARTCC.

Narrative: WE WERE TRACKING OUT TD 104 DEG RADIAL AND NEEDED TO BE AT FL330 BEFORE WE COULD GO DIRECT TO ELATO. THE CTLR TURNED US TO 020 DEGS AND WE USED ONLY 10 DEG ANGLE OF BANK TO PRESERVE OUR CLB PERFORMANCE. THEN AS WE WERE PASSING FL310 HE CLRED US DIRECT ELATO. WE WERE IN A SLIGHT R TURN TO AVOID A BUILD-UP. I ELECTED TO GO AROUND THE BUILD-UP PRIOR TO GOING DIRECT ELATO. THEN HE STARTED YELLING AT US THAT WE WERE GOING OUT OF HIS AIRSPACE INTO TAIPEI'S AIRSPACE. WE THEN WENT DIRECT ELATO. 1) OUR CLB PERFORMANCE PUT US RIGHT ON THE LEVEL AT ELATO REGIMENT. 2) OUR 10 DEG BANK TURN TO KEEP OUR CLB PERFORMANCE WASN'T ENOUGH TURN TO KEEP US OUT OF TAIPEI'S AIRSPACE BUT I WANTED TO KEEP UP OUR CLB PERFORMANCE. 3) SO WE PUT OURSELVES AT RISK. BUT I FELT HE WANTED US LEVEL AT FL330 AND THAT IS WHAT I WAS TRYING TO ACCOMPLISH.
